Manchester City stars sat through one of manager Pep Guardiola’s longest post-match inquests after the demoralising defeat at Newcastle.
The Premier League champions are understood to have been in the dressing room for about half an hour as Guardiola demanded answers following the 2-1 loss.
Sources claimed that ‘raised voices’ could be heard from inside the St James’ Park tunnel during what was described as an ‘unusually long debrief’.
Guardiola, who refuses to admonish his players publicly, was unhappy at City’s level of performance.
