The agent of Sunderland goalkeeper Simon Mignolet admits they'll consider their options in the summer.
Mignolet's representative, Guy Vandersmissen told the Belgian media the keeper may need a bigger stage in order to gain international recognition.
Arsenal and Manchester United are following the Belgium international.
"Our ambition is for Simon to play somewhere that he can engage in competition with Thibaut Courtois for the place in goal for Belgium," said Vandersmissen.
"Courtois is fortunate that he is playing for a team that has been doing well lately."
