FC Utrecht hope the rumours of big clubs moving for Swansea City goalkeeper Michel Vorm are true.

Vorm only moved to Swansea in the summer for €1.8 million, but is now being linked with giants Manchester United, Chelsea and Tottenham.

Utrecht chief Foeke Booy told RTV that a major sell-on clause is included in Vorm's deal.

"I won't mention figures, but there is more than training costs involved," he said.
