Twente boss Steve McClaren and club president Joop Munsterman are dismayed by the behaviour of Luuk de Jong, after the striker spoke out about his slow-moving transfer away from the club - with Newcastle United and Borussia Monchengladbach believed to be interested.
On Saturday, the 21-year-old slammed the president over his handling of the situation, branding the board's negotiating tactics "indecent" after they raised his asking price.
But Munsterman is resolute in his stance that De Jong will not be leaving the Grolsch Veste, and stated that no discussions have taken place.
"We have not been in talks with Borussia Monchengladbach," he told Dutch newspaper De Telegraaf.
"Why would I have spoken to them? Luuk de Jong has signed a contract with FC Twente and he must continue to train and play matches. Nothing else."

But the former England boss, who is in his second spell in charge of the Tukkers, has had his say on the conduct displayed by the wunderkid.
"This is incredible," McClaren said. "I never expected this situation. It is totally unnecessary. It is only the beginning of July. We have two months of this."
De Jong scored 25 Eredivisie goals last season.
