Sunderland goalkeeper Simon Mignolet is expected to snub a new contract offer from the club, according to his agent Nico Vaesen.

The shot-stopper previously attempted to play down a move away from the Stadium of Light amid reported interest from Liverpool, Arsenal and Manchester United.

"There is no progress," Vaesen told the Sunderland Echo. "I think it is very unlikely that he will sign a new contract. Simon has obviously come to a point where he wants to step up a level and there is a lot of interest in him.

"He is very ambitious and wants to play in the World Cup, in Brazil, next year. It was a good thing that Sunderland stayed up and it is a fantastic club where he has had three great years. But it is maybe time to step up a level and play for a club competing for a European spot."

Napoli, who are now under the leadership of former Chelsea interim manager Rafael Benitez, are also said to be keen on the Belgium international.
