Arsenal manager Mikel Arteta said his team must find a way of avoiding red cards as they cannot continue to play with ten men.
The Gunners for the third time this season had a man sent off after William Saliba saw red at Bournemouth last Saturday. Arsenal lost 2-0 their first defeat of the Premier League campaign.
“Playing with 10 men, always there is an issue,” said Arteta, whose side have conceded goals in all three games in which they have been reduced to 10 men.
“The truth is, when you analyse it, three very different actions and the outcome of them, the reasons are very different.
“Regardless of that we cannot continue to play with 10 men, especially at this level.
“We need to eradicate that, it’s clear. The reasons and how – it doesn’t matter. We have to focus and it has to happen.”
Since Arteta’s first game as Arsenal manager on 26 December 2019 the Gunners have received 18 red cards – five more than any other Premier League team in that period.
Saliba will miss the match at home against Liverpool on Sunday but can play in Arsenal’s game against Shakhtar Donetsk in the Champions League on Tuesday.
