Mourinho walks out of press conference: "I don't like this tendency that you only ask about the players not selected"— Rob Harris (@RobHarris) September 30, 2013
The Portuguese boss is preparing his side for their Champions League clash with Steaua Bucharest on Tuesday evening.
Prior to making the trip to Romania, Mourinho was met with newspaper headlines about the future of Kevin De Bruyne.
A series of reports, including one from the Metro, in the English media on Monday suggested De Bruyne had been dumped from the first-team squad and told to train with the Under-21s.
Upon his arrival in Bucharest, Mourinho was asked repeated questions about De Bruyne.
He confirmed the winger had remained in London, but when pressed again and again, he simply stood up and left the press conference.

Mourinho confirmed prior to leaving the press conference that Juan Mata, a player who has found life tough since the Portuguese's return to Chelsea, would start the game on Tuesday.
Chelsea go into the game with Steaua on the back foot, after suffering a surprise defeat to Basel in week one of the Champions League.
