Manchester United boss Sir Alex Ferguson expects teenager Danny Welbeck to gatecrash Fabio Capello's World Cup squad.

"Danny's a certainty to make it at the highest level," said Ferguson. "I have told Fabio Capello the boy will be in his World Cup squad.

"Wide left or right or through the middle, he has the intelligence, guts, athleticism and talent to do the job. He's going to be a big lad.

"He's yet to get the conformation in his thighs so he is still gangly, but he's brave enough to carry that. When he stops his growing, he'll really be something."
