You cannot predict these injuries and i think its been proven already that he had played plenty of games the 2/3 seasons prior to joining us. There is this element of risk in any transfer or any player.
A midfield of Doucoure, Allan and Gbamin would offer so much energy, physical presence whilst all having quality on the ball. Great squad depth.
Cliche but we need to look at him as new signing and as Steve mentioned not rush him back and look to utilize him in the busy december period.
