There are times when he's very impressive as you say, but even when he's impressive for me he doesn't play like a defender who's been at a top club for nearly a decade. He still seems very rash and raw at times, often relying on last ditch tackles instead of having the awareness to deal with the situation before it gets to that stage.
Obviously the constant injuries and lack of long runs in the team have severely hampered his development. In his first season i was very impressed with him and excited to see what he could develop into. But for the most part he's pretty much that same player we signed in 2011.
