Id have him back in an instant, money dependent.
He has been pushed from position to position for years and the stick he gets is ridiculous, for all that I have joined in on occasions. Stick him up top, and get the ball into him inside the box and he will score 20 a season easily. Dont move him wide, dont move him deep, dont expect him to play as a false nine, just let him play on the shoulder of the last man, helping build up the play when required, before making a b-line to the box.
Id also like to see him get fired up again and get aggressive.
