Chelsea manager Jose Mourinho walked out of a press conference on Monday afternoon after becoming angry at a question regarding Kevin de Bruyne's absence from the squad to play Steaua Bucharest.
De Bruyne was not included in the Champions League travelling party despite being fully fit, and Mourinho was pressed on his reasons for leaving the Belgian in London rather than bringing him to Romania.
Mourinho claimed he "did not like" De Bruyne's recent performance in the Capital One Cup defeat of Swindon, and berated reporters for only asking questions about players who "are not here" before he left the press room.
The Portuguese highlighted the recent obsession with the continued absence of Juan Mata as a particular subject of irritation, with no questions asked about the Spaniard now he has regained his place in the Chelsea team.
Mata could start for Chelsea on Tuesday as they bid to record their first win of the Champions League campaign, having suffered a shock defeat to Basel in their opening group fixture.
Chelsea lost 2-1 at Stamford Bridge after Oscar had provided them with the lead, and now face a battle to avoid falling at the group stage for the second successive season.
