The winter market is not over for Barca - they are looking at selling Denis Suarez. A player who has not been used much by Ernesto Valverde and who is wanted in the Premier League. The injury to Rafinha seems that it might help him but the player has received various offers from English sides which he is mulling over. Barca are allowing him to choose his destination if the transfer fee meets their demands.
Denis could have left in the summer but wanted to have another crack at Barca life, but now he realises it's time to go. Milan wanted him but only on loan. Barca are hoping to get over 10 million euros for him.
In England West Ham, Watford and Everton have asked about Denis. There is a good chance of him going.
