The Uruguay international has looked back at his troublesome relationship with the tactician and has stated that he had never before had any problems with a coach
The Uruguay international lost his starting berth at Atletico in 2010-11 due to his troublesome relationship with the club's coach and eventually left the Liga side for Inter this summer, although Sanchez Flores had already been replaced by Gregorio Manzano by then.
"He had a personal problem with me and made that very clear, although I didn't do anything wrong. I had absolutely no problems with him," Forlan told Onda Cero.
"Quique Flores has been in charge of several teams and he has had problems everywhere he has been. We all know how this gentleman works.
"Perhaps my attitude towards him wasn't perfect either, but I've never before had any problems with a coach. I'm 32 now and have already worked with several trainers."
The former Villarreal star signed a contract until the summer of 2013 with Inter on deadline day of the summer transfer window. He could make his official debut in this weekend's Serie A match away to Palermo.
