Manchester City star Kevin De Bruyne has finally revealed why he left Chelsea.

De Bruyne is arguably one of the best attacking players in the Premier League at the moment and many feel that Chelsea made a huge blunder by allowing him to leave for Wolfsburg in January 2014, following a loan spell with Werder Bremen.

The Belgian has now finally opened up about his unceremonious exit from Stamford Bridge and has revealed that he had to leave Chelsea as Jose Mourinho basically thought he was not good enough to make the grade in West London.

De Bruyne told the Daily Mail: “At the time at Chelsea I had already many, many games under my belt.

“I didn't feel I was like a normal 20-year-old because I had already played for years in Belgium and then on loan from Chelsea in Germany.

“I think they (Chelsea) had a different view than I had of myself. I was young but also experienced. If I had come through the youth then maybe I would be happy to play 10 games there.

“As far as I was concerned, I was ready to play. I have read that, for them at Chelsea, I was too young, but in my mind you are never too young. If you are ready you are ready.

“I think Eden Hazard was the same age as me when he played so it's a little bit strange to say this guy is young and the other guy is old enough to play.

“It's just another way of saying that somebody isn't good enough."
