Aston Villa defender Martin Laursen has urged skipper Gareth Barry to think twice about quitting for Chelsea or Liverpool.

"I can see how it can be a problem if one of the 'Big Four' teams comes in with £20million for one of our players," said Laursen, who will seek Barclays Premier League bragging rights over Birmingham City today.

"It would be difficult for a club like Villa to ignore that, but the final decision will still come down to the player. I think there is a good argument to say they are better off here, playing and developing every week, rather than not contributing at another club."
