Theo Walcott says Alex Oxlade-Chamberlain has the strength to feature for the England senior side after another break-taking display for the Under-21's.
After his hat-trick in the first group game between the two sides last month, Chamberlain was at his very best again and was unlucky to add to his treble in Reykjavik.
Talk has been rife this week that Chamberlain, who has already netted twice for Arsenal since his move from Southampton, would earn a call-up to the full England side for the friendly with Sweden, a step-up teammate Walcott's believes he's ready for.
"When you get the opportunities [as a teenager] you have to grab it with both hands and he has done that," Walcott said.
"He's shown what he can do in the Carling Cup games and the Champions League. He's got a good head, he wants to learn, and that's very important. He's very relaxed as well and that does him a big favour because he fits in well.
"Alex has definitely got the potential to be there [at Euro 2012].
"I don't think I deserved to go to the World Cup in 2006 but I hadn't played any games in the Premier League while Alex has played in the Champions League. He knows he has a lot to learn but he is showing very good signs at this moment in time."
