Arsenal recovered from two goals down late on to draw 3-3 with bottom side Southampton, though the Premier League leaders ultimately dropped points for a third game running.
After squandering 2-0 leads to draw 2-2 in their past two games, Arsenal found themselves behind by that same scoreline inside 14 minutes in a thrilling contest at Emirates Stadium on Friday.
Carlos Alcaraz took advantage of an Aaron Ramsdale error inside 27 seconds and former Gunner Theo Walcott added a second, before Gabriel Martinelli pulled one back before half-time.
Duje Caleta-Car added a third for Southampton, but Martin Odegaard's strike was followed up by Bukayo Saka's 90th-minute leveller, leaving Arsenal five points ahead of Manchester City – who they face on Wednesday – having played two games more.
