At 22, Walcott finds himself one of the most experienced players at the club.
"I was the oldest player on the table for dinner at Newcastle at 22 years old," he recalled to arsenal.com. "It was quite funny but I'll do anything I can do to help the young players coming through. I have been around for a long time so I know what it's all about and if I can help anyone out I will happily do that.
"This team has always been known for being so young but we cannot use that excuse anymore. We need to win something and that's the most important thing.
"It is important to have a mixture of experience and young players but the boss knows what he is doing. He has some great players that he has picked up and we didn't know where they came from. Only time will tell what the boss will do."
