At the time, Mikel Arteta's side were in a relatively good position in the game, with the scores level and the better chances mostly falling to the away side. But playing such a long period of the game with 10 men ultimately decided the outcome.

To make matters worse, Saliba will now have to serve a suspension, but he will at least be available against Shakhtar Donetsk on Tuesday.

Though it was a straight red card, the sending-off was for denying a clear goalscoring opportunity, not for violent conduct, dissent, or a reckless challenge. As a result, it's only a one-game ban, nothing more.

Saliba will be available against Shakhtar, then suspended against Liverpool, before returning for the following games against Preston North End in the League Cup and Newcastle United in the Premier League.
