Paris Saint-Germain manager Thomas Tuchel locked horns with the media after his side's style of play was questioned in victory over RB Leipzig.
The French champions were facing a must-win game in Paris to keep hopes of reaching the last-16 alive.
Neymar scored a penalty and that was all that separated the sides at the final whistle with PSG having spent large spells sat deep defending their lead.
PSG, who were beaten by Bayern Munich in last season's final, were expected to perform better in the group than they have but when it was put to Tuchel that his side could, and should, have played better, he was left furious.
'I am tired of always answering your questions,' he said. 'If you have courage, if you have balls, go and ask the players in the dressing room. The guys are dead... they played with heart.'
Neymar's penalty was one of just three shots on target Tuchel's side had all evening but the German boss refused to apologise for taking a defensive approach.
Further scrutiny arose when it became clear that PSG completed the first half with just 37.2 per cent of the possession, their lowest total after 45 minutes in a Champions League game since facing Bayern back in 2017.
'We've played 11 league games and four Champions League games, and we've had around 100 injuries during that time,' Tuchel added, citing his busy physio room as justification for his approach.
'I saw that we average seven injured players per game. The most difficult thing was to find 11 players who could make a physical impact.'
Victory puts PSG in second in Group H, ahead of RB Leipzig on goal difference with two games remaining before the knockout stage.

'We'll prepare a plan for Manchester (United). If the players feel better, we'll play a better match. If we have to defend deep again, then we'll do that.'
