After Belgian midfielder Kevin de Bruyne's transfer was confirmed by new club Wolfsburg, the young star took little time to speak out about his time at Chelsea.
Despite appearing to be one of the most gifted young European midfielders around, De Bruyne was unable to impress Jose Mourinho and break into the Chelsea first team.
A continued failure to make the pitch led to many questions being put to the Chelsea boss in the early weeks of the season, which at one point caused him to storm out of a pre-match press conference.
The Portuguese subsequently publicly criticised his young playmaker's efforts in training, despite, according to De Bruyne, never talking to him about it personally.
"My pre-season was good," the new Wolfsburg star told Belgian newspaper Het Laatste Nieuws, as reported in the Mail. "My first game too, but I still don't know why I lost my place after the game against Manchester United.
"I've also never asked Mourinho. He has never told me: "Kevin, you don't train well."
"It's a pity he told a press conference that I wasn't doing well on the training pitch. That's not me. I'm always a player who gives the full 100 per cent in training. Those remarks created a wrong image."
Despite interest from Atletico Madrid and Borussia Dortmund, it was Wolfsburg that signed a player who excelled in Germany last year with Werder Bremen, where he scored 10 goals in 33 games.
And despite Mourinho convincing him to stay over the summer, De Bruyne quickly realised that he would have to leave the Blues at the first opportunity, and not just because the absence of playing time damaged his World Cup chances.
De Bryune continued: "At the end of December I had a chat with Mourinho. He told me things about competition, training hard and there's always a chance that you will play.
"And he also told me he wasn't keen to let me go, even on loan, saying: "You're a good player." But what could I do more?
"After the press conference in Bucharest I even started training harder, even on my days off. I lost three kilos and two percent fat - although we could get everything at the club: coke, chocolate.
But with no chances coming his way, De Bruyne made his decision.
"I asked him [Mourinho] in a friendly way: "please let me go."
"I didn't leave Chelsea because I have to go to the World Cup - it could be over after three games - but just because I lost my joy."
