Villarreal have warned Premiership clubs off star goalkeeper Diego Lopez.

Arsenal, Aston Villa and Tottenham are among clubs following Lopez this season, who was again outstanding against Real Zaragoza on Sunday.

"Diego Lopez has a value in the market of 24million euros (£18.85m) and this sum is the only one that we would study for the player's possible sale," a club spokesman told skysports.com.

"We have not received a formal offer for the kid, but the presence of foreign scouts to watch our players is not rare."
