Former Chelsea midfielder John Obi Mikel says Kevin de Bruyne had himself to blame for his problems at Stamford Bridge.
De Bruyne is now regarded among the world's best players after his success with Manchester City, but as a young player his professionalism left a lot to be desired, says Obi Mikel.
"I think Kevin De Bruyne, wasn't the best trainer back then," he told the Obi One Podcast.
"He was somebody that comes to training, and probably because he wasn't playing that much, always having his head down, always angry and sulking. He was like a kid who came to the playground and nobody wanted to play with him.
"I remember when Samuel Eto'o had a go at him and they had a massive fight on the training ground just because he [De Bruyne] wasn't putting in the effort that Samuel Eto'o wanted so they had a massive row on the pitch."
He added: "When I watch Kevin De Bruyne play today I'm like 'is it the same guy!?'"
