Stoke City boss Tony Pulis has warned clubs off making a move for captain Ryan Shawcross.
Liverpool and Manchester United are both thought to be keen on luring the powerful central defender away from the Britannia Stadium.
Reds boss Roy Hodgson is believed to be keen to bring in Shawcross as a replacement for the injured Jamie Carragher.
Former club United have kept an eye on Shawcross' progress at Stoke and they are believed to have watched him in action against Wigan last weekend.
A number of foreign sides are also thought to be tracking the 23-year-old, but Pulis insists Stoke are under no pressure to sell Shawcross.
"We are under no pressure to sell and Ryan is somebody the chairman will not contemplate leaving," said Pulis.
"Ryan could not be happier here and we've also got him on a very good long-term contract.
"Obviously if we were offered ridiculous money, then any club would have to look at it. But we've had no offers as yet and wouldn't welcome any.
"We see Ryan as a major part of our future. He's only progressed since coming here and is now the club captain."
