Manchester United defender Rio Ferdinand says Theo Walcott and Emmanuel Adebayor are Arsenal's danger men ahead of tomorrow's Champions League tie.

Ferdinand said: "Theo could be a sprinter. He's one of the quickest I've ever faced.

"Playing against Adebayor is a challenge, too.

"He's quick, he's got good movement and is strong so we'll have to be on our A-game to make sure we combat him.

"But we're ready for them and everyone else in an Arsenal strip.

"They'll be two great games. Two English teams vying to get into the Champions League final, you can't ask for much more."
