Arsenal midfielder Tomas Rosicky says Theo Walcott must learn to handle the hype.

He said: "Walcott is terribly unpredictable with his speed. Occasionally he lacks a little calmness but people always forget he's only 19.

"When he plays well, they say he's like Maradona. Then he has two bad games and they write he's not improving at all and that he is stagnating. The truth is somewhere in between."
