Wenger expects him to shine in the Premier League.
"I bought him because he's a real centre forward and he is an intelligent player," Wenger told Arsenal Player.
"He is a player who developed late and I feel he can integrate in the way we play football and add something to the way we play because he is good in the air.
"He has a good, strong body and I feel he has qualities that are needed in our squad. Hopefully he can show that."
