Just a thought. He was without doubt one of the best central defenders of his generation. Retired now and two dodgy knees. Would it be worth him coming out of retirement till the end of the season as a back-up? Even with dodgy knees he's a cut above anything we've got and could do a job...
Fits in well, can't train, can only play every other game even when fit! Real shame because he was a great defender but Injures never allowed him to show it.
If he signed for you then he would be your best defender by a mile dodgy knees or not. The man is a beast. More likely is Michael Dawson going to QPR in January. He has a great attitude and gives 100% from the first minute to the last.
