Not for the first time in a North London Derby, one side failed to keep all 11 players on the pitch.
In the meeting at the Tottenham Hotspur Stadium back in May, it was Arsenal who were reduced to 10-men when Rob Holding was given his marching orders for two bookable offences as his plan to nullify the threat of Son Heung-min ultimately backfired and resulted in him heading for an early shower.
But at the weekend, it was Spurs' discipline that came into question as Emerson Royal was shown a straight red card following a nasty tackle on Gabriel Martinelli and to make matters even worse for Antonio Conte, moments later Granit Xhaka put the game to bed with his second goal of the season.
