Nigeria striker Nwankwo Kanu has a groin problem

Kanu is suffering from a groin strain which threatens to rule him out of an emotional return to Arsenal, where he spent four years of his career.

Kanu said: "It will be nice to go back there and see a lot of old friends, but I am struggling at the moment.

"I spoke to some of the Arsenal boys and told them I wouldn't be there because I was injured, which they laughed at.

"But I hope I will see them there on Saturday. If I go back to Highbury it will be something special for me."
