Cabaye injury??

Id put it down to the adrenaline of the sheer anger him getting back up. If you watch him get up when he puts weight on the foot he stumbles. Looks to me like there was sufficient pain in putting pressure on the foot to let him know something was not right.
You dont always need to be writhing on the ground in agony to realise you have injured yourself

 

I hope so or he was just being a pussy, something I have not associated with him so far. As long as he's fit I don't mind but he is going to have to accept that he will be tackled, and the odd one (like his own) isn't going to be the best. I'll give him the benefit of the doubt and say it was a painful blow on an ankle he's had a little bother with.
