I do think he's good enough for us. He's strong, excellent on the ball, he's not slow and he's versatile enough to play as a left back or a defensive midfielder, apart from central defender. He was the best player of the Eredivisie, though that's not much of an achievement. He would suit us, I think. He only lacks concentration at times, but that's not strange if you play in the Eredivisie. Some clubs don't even reach the Ajax goal, so it's understandable. He wouldn't be too expensive, because his contract expires in a year, so he might be relatively cheap too.
