Arsenal boss Arsene Wenger insists Theo Walcott can make it at Emirates stadium - despite dropping him for Saturday's victory over Fulham.
"I am amazed that people are surprised that he is a little bit frustrated when he doesn't play.
"It is part of his job and part of his improvement."
Wenger told Arsenal TV Online: "Overall I am very happy with him, I have said many times that he will be a player through the middle, a striker, because the timing of his runs, the quality of his runs is fantastic and he is clinical finisher.
"The time he spends on the right will help him became a fantastic striker."
