Just looked on transfermarkt, the man is brittle.
16/17 he hasn't played.
15/16 he was available to play 17 times out of 52 possible games with 4 different injuries.
14/15 he was available to play 15 times out of 57 possible games with 3 different injuries.
13/14 was his last proper season, available to play 47 times (played 30) out of 55 possible games with just 2 injuries.
12/13 he was available to play 43 times (played 22) out of 53 possible games with 5 different injuries.
11/12 Available every game.... that can't be right.... played 32 out of 47 possible.
If there's one thing we're sure of, we don't mind taking a risk relying on injury prone players and those recovering from long absence. Not sure I agree with it long term, but in the situation we're already in, I'd rather have hime here than not.
