Oxlade-Chamberlain made a surprise appearance for his country in England’s 1-1 draw against France on Monday. The youngster's performance was impressive for the most part and could see him play a vital role in the Three Lions' Euro 2012 campaign.
The Arsenal winger is likely to build on his first competitive international match with a start in England’s next Group D clash with Sweden, which takes place on Friday.
Rosicky is confident his Gunners team-mate will continue to improve his game with experience gained from England's tour of Poland and Ukraine.

"Of course I'm excited to see him getting his chance," Rosicky told Sky Sports.
"He's a very young boy and it's great that he's here and he can gain experience like that. For a boy his age it's vital to get experience like that. So Arsenal can profit from that.
"He's not the finished article, he has lots to learn but he is an amazing prospect and I just hope that he will work and he will grow.
"As I know him, he has both feet on earth and he's very confident.
"Even if you are like that, a tournament hits you anyway a little bit but that's what you expect."
