Tottenham boss Andre Villas-Boas says they won't pay Porto's asking price for Joao Moutinho.

Moutinho was expected to be the focus of their attention on deadline day, but Tottenham appear unlikely to sign the 25-year-old due to a 40million euro (£31.7million) release clause in his contract.

"It's an impossible deal for the club," Villas-Boas told a press conference.

"You have to bear in mind that this is a player with a 40million euro release clause.

"This volume of money is out of Tottenham's possibility.

"Bearing in mind that this is a key player for club and country, you wouldn't say that you would get him at half the price and half the price is already bigger than Tottenham's record fee."
