Pep Guardiola was spotted deep in conversation with defender Josko Gvardiol on Wednesday night, as he was clearly intent on hammering home a point or two player despite already having won the match.
Guardiola has earned himself a reputation as one of the most demanding perfectionists in football, and has developed a habit of delivering post-match grillings on the field.
On Wednesday it was at the scene of his side's victorious return to the Premier League, coming from a goal down to beat Everton 3-1 at Goodson Park, having won the Club World Cup the previous week.
