if niasse isnt fit he isn't fit, stop getting all mad about it.
Would you rather he was rushed in, was crap and it knocked his confidence or would you rather he came in when he's adapted a little bit and got some fitness behind him.
I posted something a couple of days ago and it was just a small paragraph with Martinez saying he would have to be checked on Friday to see if he can make the squad.
I gathered from that he's not match fit enough to take the place of a Kone on the bench yet.
