Arsenal legend Pires: Chamakh will be big success
World Cup and European Championship winner Pires played for five years at Arsenal and admits the first six months left him bewildered on occasions - just as it did to Thierry Henry and Dennis Bergkamp before him.
Pires said: "Marouane will be a big success at Arsenal, I am sure of that. It's difficult when a player arrives from a league like the French Championnat. It is so different to the English football. It can take you by surprise.
"The most difficult thing is the speed of the game, but then there is the physical side. You have to give people time to adapt."
Pires added: "I've got to know him as I've been training with Arsenal. He has all the qualities that are needed to be a success in England.
"He has character, an excellent touch and technique and he's already shown that he can score goals.
"He knows he has to defend at times as well as attack and he is willing to do that.
"That is why I am certain that he will be a big success at Arsenal."
