The last time England toured Sri Lanka, they were attempting to fine-tune their plans for the 2015 World Cup. It's fair to say things didn't quite go to plan in a 5-2 series defeat and the fortunes of the squad involved diverged significantly.
Alastair Cook
What happened? Struggled throughout the series, scoring 119 runs in six innings (he missed one match through an over-rate suspension) at a strike-rate of 67. Paul Downton, the managing director of England cricket, admitted Cook was having a "terrible time" but added "I would be very surprised if he was not captain at the World Cup." After the final ODI, Cook said: "I can't have any complaints if the decision went against me."
What happened next? Three days after the tour, Cook was sacked as ODI captain and replaced by Eoin Morgan. "I am gutted to be left out of the World Cup squad and it is likely to take me a while to get over the disappointment," Cook said.
Where is he now? On the farm. Cook remained England's Test captain until late 2015 and brought down the curtain on his international career with the final Test against India last month.
Moeen Ali
How did he do? Moeen, who was opening the batting, started the series with a bang as he made his maiden ODI century and followed that with a fifty before fading a little. With the ball he managed five wickets in seven matches.
What happened next? He opened throughout the dismal World Cup campaign, scoring a century against Scotland.
Where is he now? A central part of England's one-day side, forming a regular dual spin attack alongside Adil Rashid and providing striking power down the order.
Alex Hales
How did he do? Despite having shown his white-ball power with England's first (and still only) T20I hundred, Hales did not start the series and only featured in three matches making scores of 27, 0 and 7.
What happened next? Was once again sidelined during most of the World Cup, only called up for the final two matches including England's elimination against Bangladesh.
Where is he now? Has become a fearsome one-day batsman and briefly held the record for England's highest individual score (171). However, given England's batting strength he is not certain of a starting position. Also has the outcome of the CDC hearing, in relation to the brawl in Bristol last year, hanging over him.
Ian Bell
How did he do? Was dropped after the first two matches of the series.
What happened next? Returned to open in the World Cup build-up - making a career-best 141 against Australia in Hobart - and went on to be England's highest scorer at the tournament.
Where is he now? The final match of his World Cup, against Afghanistan, was his last ODI as he was moved aside in the shake-up. Remained in the Test side for another year before being dropped in late 2015 and has not returned.
Joe Root
How did he do? A shining light in the series with 367 runs at 73.40 including an unbeaten hundred to secure victory in Pallekele.
What happened next? Much hope rested on Root's shoulders at the World Cup and he scored another century against Sri Lanka, but couldn't save a failing side.
Where is he now? The glue around England's thundering batting line-up. Averages over 50 in ODIs and though there were a few murmurings about his position during a brief lean spell earlier this year, those were emphatically put to bed by back-to-back matchwinning hundreds against India.
Eoin Morgan
How did he do? Had a poor series with bat with 62 of his 90 runs coming in one innings - the match when he was captain. It extended a lean run of form that stretched back into the previous English season.
What happened next? A few days after the tour was completed, Morgan was named England's one-day captain. "I firmly believe that with the players currently involved in the one-day set-up, we have the makings of a very good one-day side, a young side that can surprise people at the World Cup," he said.
Where is he now? Has established himself as England's finest ever one-day captain. In terms of his batting, others have now surpassed his once trend-setting style and his form dips are often highlighted, but his place is never in danger.
James Taylor
How did he do? Having played just two ODIs in three years since his debut, he came in midway through the series and made an immediate impact with scores of 90 and 68.
What happened next? Prepared for the World Cup batting at No. 3 before, on the eve of the tournament, being shunted to No. 6. Responded with an unbeaten 98 in Melbourne but didn't flourish after that. Captained England in their first post-World Cup match (against Ireland) then had a run in the side in late 2015 which included a maiden hundred against Australia.
Where is he now? Taylor's career was brought to an abrupt halt in sad circumstances in early 2016 when he was forced to retire after being diagnosed with a serious heart condition. After working in the media for a time, he is now an England selector.
Ravi Bopara
How did he do? Scored half-centuries in England's opening two defeats of the series which led to him being shifted up the order.
What happened next? Drifted out of the side in the build-up to the World Cup as England made the late decision to play Gary Ballance. Only appeared for the final match against Afghanistan.
Where is he now? The World Cup marked the end of Bopara's stop-start England career and he now pops up in various T20 leagues while continuing with Essex.
Jos Buttler
How did he do? Was already establishing himself as a cut above England's other one-day batting, having scored a record-breaking hundred against Sri Lanka the previous summer. Played one match-winning hand in this series when it often felt like Buttler or bust.
What happened next? Almost saved England in the Bangladesh run-chase, but his dismissal was the end for them.
Where is he now? One of the most devastating batsmen in the world and among the finest one-day finishers. Has plundered five ODI hundreds since the World Cup, including breaking his own England record with a 46-ball century against Pakistan.
Ben Stokes
How did he do? Three matches, two innings, 22 runs; eight overs for 85. It said plenty of England's one-day mess that they couldn't work out how to get the best from Stokes, although the early days of his ODI career had not been convincing.
What happened next? Stokes was left out of the World Cup squad and, though his form had been poor, there were plenty of pundits who knew then that England had got the decision wrong.
Where is he now? Established in England's middle order, usually around No. 5, and now has three one-day centuries while being an important, if sometimes inconsistent, option with the ball. Was found not guilty of affray earlier this year following the fight in Bristol last September, but along with Hales still faces a CDC hearing which could yet impact availability next year.
Chris Woakes
How did he do? A rare positive on the tour as Woakes emerged as a one-day bowler of considerable skill, taking 14 wickets.
What happened next? Was a regular feature of the World Cup side and with the bat was unbeaten on 42 when England were knocked out.
Where is he now? Missed the entire white-ball summer due to injury having established himself as the team's leading new-ball and death bowler. Likely to slot straight back into the side.
Chris Jordan
How did he do? Was England's second-leading wicket-taker with 10 scalps in five matches having not started the series.
What happened next? Did not feature until the back-end of the World Cup, playing against Bangladesh and Afghanistan. Was then in and out of England's new-look one-day side for a year.
Where is he now? Has drifted well down the ODI pecking order where his skills at the death are not enough to compensate for less effectiveness elsewhere, although he remains a regular part of the T20 set-up.
James Tredwell
How did he do? Was England's most economical bowler in the five matches he played, although he had limited wicket-taking impact.
What happened next? Only came into the World Cup side for the final match, with England opting for Moeen as the frontline spinner.
Where is he now? Despite having an ODI record on a par with Graeme Swann, he did not play again. Retired from the game after the end of the 2018 season due to a persistent shoulder injury.
James Anderson
How did he do? Was named in the original squad but withdrew with a knee injury to recover in time for the World Cup.
What happened next? Showed promising form during the tri-series in Australia but was wicketless in the group matches against Australia, New Zealand and Sri Lanka.
Where is he now? One of the biggest calls made after the World Cup, Anderson's one-day career came to an end. However, his Test career has gone from strength to strength and he recently became the leading pace bowler in the game's history.
Harry Gurney
How did he do? England were keen to bring some variety to their attack with a left-armer and Gurney had shown some promise during his first summer, but did not prove a long-term answer. He took 1 for 158 off 24 overs in three matches in Sri Lanka.
What happened next? He didn't make the World Cup squad and hasn't played for England since.
Where is he now? Remains a key part of the Nottinghamshire attack in all formats and also co-owns pubs with Stuart Broad.
Steven Finn
How did he do? Put in some hard yards in tough conditions over the five matches he played, although only managed five wickets.
What happened next? Looked in good rhythm during the World Cup preparation with a five-wicket haul against India. Opened the World Cup with another five-for, against Australia, but by then the score, at 342 for 9, was out of sight. Finished the innings with one of the more forgotten hat-tricks in history.
Where is he now? Struggled to nail down a regular place due to injury and form. Has battled fitness issues since withdrawing early in last year's Ashes tour and had a truncated 2018 season. May struggle to return to England colours.
