Blackburn Rovers defender Martin Olsson has turned up the heat ahead of tonight's U21 European Championship semifinal between Sweden and England.

Olsson has taken a swipe at Arsenal star Theo Walcott, rapping: "He is extremely fast but not as good as everyone says.

"It's the players around him that feed him and make him good, so if we can shut them down, I think we can prevent him from getting those passes.

"Against Finland, he had almost no chances and wasn't that much of a factor. There's no Adebayor who can help him. The other players are young too and they also make mistakes."
