Big picture
Unpredictable sides make for great knockout games, so the Bangladesh-Pakistan encounter in Abu Dhabi, which will determine India's opponents in the final, is unlikely be any different. Pakistan can be a dangerous side in crunch situations while Bangladesh would see making the Asia Cup final a big step in their progress as an ODI force, especially with the World Cup now eight months away.
Not making the final would be seen as a backward step for Pakistan's ODI set-up, especially after their Champions Trophy triumph last year. But so far their average Asia Cup campaign goes with their recent trend of extreme highs and lows from series to series. In October last year, they beat Sri Lanka 5-0 before being blanked 5-0 by New Zealand. They beat Zimbabwe 5-0 in the last ODI assignment before the Asia Cup where they have won against Hong Kong and Afghanistan, but lost both times to India and comprehensively so.
Mohammad Amir going wicketless in his last six ODIs has been surprising, while Hasan Ali, the only quick bowler picked in every game in the Asia Cup, has taken three wickets at 51.66 each. Shadab Khan therefore has to take up responsibilities against a Bangladesh batting line-up that can be susceptible against legspin.
Pakistan would also have to pick up their fielding, having dropped too many catches in their last two matches against Afghanistan (five) and India (three). On top of these bowling and fielding woes, Pakistan also needs runs from three batsmen among their regular top six.
Fakhar Zaman, who made a record 210 against Zimbabwe in July, has so far made just 55 runs in the tournament. Captain Sarfraz Ahmed and Asif Ali have made 58 and 46 respectively, in the four matches so far. Runs have mostly come from Shoaib Malik, Babar Azam and Imam-ul-Haq, but against Bangladesh's efficient bowling line-up they cannot afford a top-order collapse or a poor finish.
Bangladesh are at times susceptible in their death bowling aside from Mustafizur Rahman, whose skillful mix of slower balls, yorkers and bouncers troubles big-hitters. Mashrafe Mortaza and Mehidy Hasan Miraz often keep it tight in the first Powerplay while Mustafizur, Shakib and Rubel keep the run-rate down in the middle-overs.
But Bangladesh become a stronger bowling unit when they post at least a competitive total. Liton Das' 41 would be encouraging for the team management but his opening partner in the last three games, Nazmul Hossain Shanto, has made a poor start to his ODI career with just 20 runs.
As a result, Imrul Kayes, who made 72 batting at No. 6 for the first time in his career in the previous game, may be sent to No. 3 with Mohammad Mithun reverting back to No. 5. It would mean they have two senior batsmen in Imrul and Shakib in the top four, while the in-form Mushfiqur Rahim and Mahmudullah have the capability to stop a batting collapse or, in a better situation, go after the bowling in the last 10 overs.
Neither team can however be assured of everything going to plan. They are unpredictable and at times flawed, which usually makes for gripping viewing.

In the spotlight
Mustafizur Rahman's last-over heroics handed Bangladesh the win against Afghanistan, and bowling in the last five overs is fast becoming his biggest strength. In the last three years, he has been one of only two bowlers to have an economy rate of under six per over during that period in ODIs.
Shoaib Malik has been Pakistan's main scorer in the tournament, having made 181 runs in four matches. He would also want to improve his ODI record against Bangladesh, having scored just one half-century against them in 13 innings.
Team news
Bangladesh usually doesn't make changes when they have just won a game, especially when they are playing at the same venue.
Bangladesh (probable): 1 Liton Das 2 Nazmul Hossain Shanto, 3 Mohammad Mithun, 4 Shakib Al Hasan, 5 Mushfiqur Rahim (wk), 6 Imrul Kayes, 7 Mahmudullah, 8 Mashrafe Mortaza (capt), 9 Mehidy Hasan Miraz, 10 Nazmul Islam, 11 Mustafizur Rahman
Batting and bowling woes may tempt Pakistan into trying out Shan Masood and Junaid Khan for the first time in the tournament. But it also doesn't mean the likes of Faheem Ashraf, Haris Sohail and Usman Khan can't be hopeful of a place in the XI.
Pakistan (probable): 1 Imam-ul-Haq, 2 Fakhar Zaman, 3 Babar Azam, 4 Sarfraz Ahmed, 5 Shoaib Malik, 6 Asif Ali, 7 Shadab Khan, 8 Mohammad Nawaz, 9 Hasan Ali, 10 Usman Khan, 11 Shaheen Shah Afridi
Pitch and conditions
Only Pakistan have won while chasing in Abu Dhabi in the four Asia Cup games held here so far, so it remains a bat-first ground. There will be no let-up in the heat.
Stats and trivia
Pakistan have won 31 out of 35 ODIs against Bangladesh, but three of those four defeats came in the 2015 ODI series.
Shakib Al Hasan's direct hit that ran out Rahmat Shah in their previous game was only Bangladesh's third run-out with a direct hit in the last 12 months. Shakib has two of them, Imrul Kayes the other.
Shoaib Malik is 54 runs away from eclipsing Younis Khan's 7,249 runs, which will take him to sixth place in Pakistan's all-time ODI run-scorers list.
Quotes
"Pakistan are a tough cricketing nation and want to put things right. I did read some comments from Mickey Arthur about some of their tactics and that's the very reason I am trying to not give our tactics away. But I know what he wanted his bowlers and batsmen to do and they did not do it in those games. They are a good team and they can very much bounce back."
