Radja Nainggolan has slammed Sevilla sports chief Monchi.

Nainggolan was signed by Monchi when he was in charge of AS Roma.

"The other one (Monchi) came from the sports director who ruined the team. He sold all the players. I can't even name him. If I had known that he would be leaving soon after, I would have stayed. If I went back to Roma now, I could ruin a wonderful memory that I have," said the veteran.

“We had very strong players and then we sold them. These things happened every year because of the budget. If you want to win with strong players, you have to keep them. If you always change, you will never have a solid basic structure.

“I still don't think about retiring. But I think it's never easy. Every player wants to finish in a good way. Sooner or later the farewell reaches all the players. I haven't thought about leaving yet, but I'm not afraid to one day."
