The day before the game, Mikel Arteta relived some of the happy times he had spent as a young player at Paris Saint-Germain in the early 2000s.
He talked about his respect for the coach, Luis Fernandez, who gave him his first real chance as a young player and he talked about the joy of playing with Ronaldinho.
The two men were roommates for 18 months and it was part of his job, Arteta intimated, to keep the party animal in the brilliant Brazilian at bay.
Old habits die hard, it seems. Arteta was it again on Tuesday night when PSG came to north London. There he was, once more, spoiling all the fun.
It was a miserable evening for Luis Enrique and his French champions as Arsenal swept them aside in the first half and kept them at bay in the second when they rallied.
