Arsenal started their Champions League campaign with a respectable draw against Paris St Germain, with Alexis Sanchez scoring a late equaliser at the Parc des Princes as both sides finished with 10 men.

The Gunners got off to the worst possible start when Edinson Cavani headed the hosts ahead inside a minute but he went on to waste a number of golden opportunities before Sanchez struck to snatch a draw late on.

This match was a mess.. Thank God, Sanchez at least saved the day by giving us a point.. 1st point in last 3 #UCL opening games for us..

There was late drama as Arsenal substitute Olivier Giroud tangled with Marco Verratti in an off-the-ball incident which saw them both sent off by referee Viktor Kassai.

And that is how not to referee #PSGvAFC

The referee has ruined the end of that game. No need for either player to go. Poor. #PSGvAFC

Have you ever seen a ref that petty? 🙄

Arsene Wenger spoke in the last week about the maturity of his squad and they certainly showed their steel to take a share of the spoils from a game they could easily have lost by a significant margin.
