Groningen have told Kiran Bechan and Jack Tuyp they can leave the club, despite the fact both have a great deal of time left on their current contracts.
Striker Tuyp arrived at the club from Volendam in 2004, but he has failed to make the breakthrough.
He is now back on loan at Volendam - but he has been informed he can leave despite have three years left on his current deal.
Bechan, like Tuyp, arrived in 2004, when he signed from Ajax - but he has failed to make the expected impact.
Bechan, who has two years left on his deal, had talks with great outfit Xanthi in January and is expected to leave in the summer.
