Arsenal and Leeds United clashed in a 2020-21 English Premier League football match on Sunday night, with "The Gunners" holding "The Whites" to a goalless draw despite being down to 10 men.
Arsenal winger Nicolas Pepe left his team a man short after he headbutted Leeds defender Ezgjan Alioski just six minutes into the second half of the game.
Arsenal manager Mikel Arteta described the incident as "unacceptable".
"We knew the level of intensity, aggression, and how alive Leeds are in every action. You need to be able to deal with that because it's part of the plan against this team", Arteta said.
Despite the match ending in a draw, Arsenal fans lashed out at Arteta, saying that the problem is the manager, and called for him to be sacked, with the hashtag #ArtetaOut trending on Twitter.
In the first 9 games of the season, Arsenal has only scored 9 goals, their worst start to a league season in terms of goal scoring since the 1998/99 season.
