His agent Rob Jansen has denied that a deal is in place with Atletico, insisting nothing has been agreed about his future.
"It is not true. We have not reached any agreement with any club whatsoever. So not even with Atletico Madrid," he told sport-promotion.nl.
"I cannot comment whether in the candidates there is Atletico Madrid. That would be wrong, in my opinion.
"We're working on it now. That is the current state of affairs. But again, decisions haven't yet been taken."
