Chelsea boss Jose Mourinho has lambasted Romelu Lukaku for constantly talking about his Stamford Bridge exit.
Mourinho is unhappy with the way Chelsea loanee Lukaku has publicly spoken about his decision to leave the Blues.
Lukaku moved to Goodison Park on deadline day on a season-long loan deal, much to the surprise of Chelsea fans and pundits.
The 20-year-old said back in October that Mourinho forced him to leave Chelsea on loan as he was not part of the Portuguese tactician's plans.
Speaking to Belgian newspaper Nieuwsblad, Lukaku said: "I couldn't do much about it. The coach made his choice, and, as a player, you have to respect it. I went along with it, and it is now up to me to prove he was wrong.
"It has been two years in a row now, and it does make you question things and wonder why. But that's life. You just have to get on with it.
"The only thing I can do is play well and score as many goals as I can, and then maybe people will notice what I am about."
Mourinho has not taken to the criticism well and has asked Lukaku to clarify his comments.
"Romelu likes to speak. He's a young boy who likes to speak," said Mourinho.
"But the only thing he didn't say is why he went to Everton on loan. That's the only thing he never says.
"And my last contact with him was to tell him exactly that. I said 'Why do you never say why you are not here?'
"So it's something he should talk about because he likes to speak. It's something he should say, the reason why he's not with Chelsea and is in Everton."
The former Real Madrid manager's decision to send Lukaku out on loan seemed baffling, as he only had forwards Fernando Torres, Samuel Eto'o and Demba Ba at his disposal.
However Mourinho has suggested that Lukaku - who has scored seven goals in nine games for Everton - asked to leave Stamford Bridge.
