Dubbed 'Spiderman' because he likes to wear the superhero's mask in his goal celebrations, the former Real Mallorca star has been told he cannot carry it in any fixture in England.
Keegan: "I am dying to see his Spiderman because it means he has scored, although I won't hold my breath because he has only scored four times in 90-odd games.
"But I really like him. He has been accepted from the first minute he came to the club.
"Instead of being a boy looking round, he was a man who knew he could play.
"Too often in the recent past we have bought players who have not been quite good enough.
"They have either not settled or not understood what it means to play for Newcastle.
"You can't just say good players can play at Newcastle because history will prove they cannot."
