Arsenal boss Arsene Wenger wants Alex Oxlade-Chamberlain to work on the defensive side of his game.

The 18-year-old was outstanding in the Carling Cup on Tuesday night, causing Manchester City plenty of problems with his pace, direct running and eye for goal.

"Defending is not his preferred side but unfortunately at the top level today you have Messi doing it, Rooney, Ronaldo, Van Persie - so why should he not do it?" Wenger told Arsenal Player.

"There is no other way to succeed anymore. That's why, of course, I believe he has the quality to do it. He has the physical ability and he is not scared to go into challenges. He can take a challenge.

"To add that to his game will make him stronger because he will win some balls in areas where he can be dangerous. He's a player who has an impact.

"If you look at the whole picture when you think him, Frimpong, Coquelin, Ramsey and Wilshere just in midfield - we have absolutely exceptional talent and it's very important that we continue to develop them very well."
