Roma midfielder Radja Nainggolan says he's quitting Belgium.

Nainggolan confirmed he is retiring from international duty after another snub from Belgium Coach Roberto Martinez.

“He called me at 11.00 (one hour before the squad announcement, ndr) and said he had the impression I was not focused enough on playing for the Red Devils during the World Cup matches in June. I was about to explode when I heard that," Nainggolan told Nieuwsblad.

It was reported Martinez turned on him when he arrived late for a tactics session ahead of the Estonia game.

“He didn't mention it, but we only talked for a minute, no more than that. As for Estonia, I was waiting for the lift for 37 seconds and was late. Other players were late too, I was not alone. It's always something.

“I am going to stop international football now. It makes no sense. He calls Youri Tielemans who is sitting on the bench and playing only a few minutes at Monaco.

“When he was appointed, Martinez said that the Red Devils must play in top competitions. Now that Axel Witsel is in China, suddenly that doesn't apply anymore. That's all fine, but I have to step up my game? Come on.

“Actually, I was in the same restaurant as Martinez in Ibiza. He did not say hello or goodbye, neither did I. How can you work together like that?"
