AC Milan are threatening Barcelona's deal for Palmeiras striker Keirrison.

Corriere dello Sport says Keirrison's management company, Traffic, have turned down an offer from Barcelona for the 20 year-old.

Milan chief Leonardo has been in contact about Keirrison's situation with the view to the youngster eventually succeeding veteran Pippo Inzaghi at the San Siro.

"Keirrison is maturing well," said Leonardo. "I'm impressed that he can play with both feet."
