Arsenal legend David Seaman has warned that Bukayo Saka's penalty miss at the weekend could prove pivotal in the title race.
The Gunners drew 2-2 against West Ham United away from home on Sunday.
They were 2-0 up in the game and could have been 3-1 up had Saka converted his spot kick.
He missed his penalty and West Ham went on to equalize and grab a point.
Seaman told his Seaman Says podcast: You know what, the West Ham result feels worse than the Liverpool one.
They were supposed to have learned their lessons from last week. That's what was really annoying.
If we don't win the league, that will be remembered as a pivotal point.
The first half an hour we were fantastic. But we didn't go up a gear, we went down a gear. We took our foot off the gas and it's disappointing."
