However, the midfielder warned that there was no “concrete” offer.
De Jong’s brother Luuk spent the season on loan from Borussia Monchengladbach and was a total DISASTER.
Siem de Jong has a year left on his contract and was quoted in Holland’s Soccer News saying: “I really do not know what I’ll do next season. I have spoken with the club but nothing is sorted.
“Also with Newcastle United, where my brother played last time, talked about other clubs and have had a little contact with my agent. There was contact before, but it’s nothing concrete.
“I do not know if he Luuk be there. He is employed by Mönchengladbach and has not received a contract offer from Newcastle, I’m going next week to talk to Ajax, then I’ll see.”
