Things change in the blink of an eye in football. The Football Whispers Index takes the latest transfer rumours and gives them a score out of five; the higher the score, the more realistic and reliable the whisper.
Here are today's top five emerging whispers. And keep an eye on Transfer Talk for all the latest gossip.
Thomas Lemar to Liverpool
Monaco winger Lemar has been a Liverpool target since last summer while Arsenal also launched a bid on the final day of the window. According to Le10Sport, the 2017 Ligue 1 winners have agreed a deal in principle to sell Lemar to Liverpool this summer. The report claims the final touches are being put on the agreement which will see Lemar head to Anfield when the season ends, ending a year-long pursuit.
Laurent Koscielny to Atletico Madrid
Regardless of whether under-fire manager Arsene Wenger remains at the Emirates beyond this summer, defensive improvements are needed. The Gunners have, according to Diario Gol, targeted Atletico Madrid centre-back Jose Gimenez. However, Atletico will demand French international Koscielny in exchange if they are to let the Uruguayan defender leave the Wanda Metropolitano. Gimenez is believed to be open of the idea of leaving Atletico.
Alessio Romagnoli to Chelsea
An upgrade at centre-half will be high on Chelsea's shopping list this summer. Skipper Gary Cahill is showing signs of decline while David Luiz has fallen out of favour under Antonio Conte having struggled to replicate last season's form. One option is Milan's Romagnoli. The 23-year-old has been impressive alongside Leonardo Bonucci this term and part of a Milan defence which has kept six consecutive clean sheets. According to Italian publication Leggo, Chelsea have been watching the Italian international closely in recent weeks ahead of making an offer.
Abdoulaye Doucoure to Manchester United
French midfielder Doucoure has been one of the stars of Watford's season and the 25-year-old is now attracting admiring glances from some of the Premier League's biggest clubs. Doucoure has already confirmed on French television that Arsenal, Liverpool and Tottenham Hotspur have expressed an interest. Now, according to the Daily Mirror, he is a Manchester United target too. The report claims the Old Trafford side had a scout present at Vicarage Road on Saturday as Javi Gracia's side beat West Bromwich Albion 1-0. Watford have already begun contract negotiations with the midfielder but fear losing their seven-goal top scorer.
David Alaba to Barcelona
Bayern Munich left-back Alaba has opened the door to the possibility of leaving the Bavarian giants with Barcelona leading the chase for the Austrian international. The Catalans are long-term admirers of the 25-year-old and look set to reignite their interest this summer. "I am aware that this decision will come to me," Alaba told Austrian outlet Kurier. "I still feel very comfortable here, but I can also imagine taking a different path, taking the next step or looking for a new challenge. But I leave that decision open."
