Arsenal's slim chances of competing for the Premier League title took a big hit after a 1-1 draw with Brentford at the Emirates Stadium.
Just four days after their impressive 3-0 victory against Real Madrid in the Champions League, Mikel Arteta's team were brought back down to earth with a draw that leaves them 10 points behind Liverpool, who have played one game less.
Thomas Partey scored first for Arsenal in the 61st minute, but Brentford equalized through Yoane Wissa 13 minutes later.
The draw means Liverpool could extend their lead to 13 points by winning against West Ham at Anfield on Sunday.
Liverpool could potentially secure the title next weekend if Arsenal lose to Ipswich, and if Arne Slot's team defeat West Ham and Leicester in their upcoming matches.
Arteta, who made five changes to the team that beat Madrid, was visibly passionate on the sidelines, urging his players to lift their performance after a slow start to the game.
The first clear chance fell to Brentford when Bryan Mbeumo set up Kristoffer Ajer, but Arsenal goalkeeper David Raya made a crucial save.
Although Kieran Tierney found the net with a header before the half-hour mark, the goal was disallowed for offside following a VAR review.
There was controversy when Christian Norgaard escaped a red card for a risky challenge on Gabriel Martinelli, leaving Arteta frustrated with the referee's decision.
Brentford goalkeeper Mark Flekken made important saves to deny Arsenal, including a shot from Declan Rice just before half-time.
Both teams had opportunities to score in the first half, but the score remained tied at the break.
Arsenal needed a breakthrough and eventually got it when Thomas Partey found the net following a quick counterattack from a Brentford corner.
However, Brentford responded swiftly with Yoane Wissa equalizing after a cross from Nathan Collins.
Arsenal had chances to secure the win late in the game, but Brentford's defense held firm, and the match ended in a draw.
The focus now shifts to Arsenal's upcoming Champions League quarter-final second leg against Real Madrid, where they will look to overturn a deficit and advance in the competition.
