I really like Dendoncker, think he'd be a very shrewd signing if for around £15m and on a 3 year deal.
He's a purely defensive-midfielder who has shown he can play as centre-back as well (in a 2 or 3). Out-and-out ball-winner, he adds nothing at all creatively (that's a GIGANTIC hole we have to fill) but we need someone to go in that middle-three and just get bloody stuck in also. He'd do that, a real steady-eddy player. Reminds me a bit of Carlsey actually, never a headline-grabber but by-God did he do some absolutely vital jobs in the side.
Lage tried him as a box-to-box type last year and it was obviously not what he was suited too so don't let any recent stats be how you judge him. I think he'd be solid as a rock for us.
