Yerson Mosquera's 94th-minute own goal clinched a dramatic 2-1 win for Arsenal over bottom side Wolves to send the Gunners five points clear at the top of the Premier League.
Wolves appeared to have snatched a sensational point when substitute Tolu Arokodare's 90th-minute header cancelled out Sam Johnstone's earlier own goal to stun the Emirates Stadium.
But Arsenal hit back as Bukayo Saka's cross was inadvertently headed into his own net by Mosquera under pressure from substitute Gabriel Jesus to spark wild celebrations.
A draw, against a side without a win in the Premier League this season, would have given second-placed Manchester City the chance to go top by beating Crystal Palace on Sunday but the late victory puts the pressure back on their rivals.
It was a cruel outcome for Wolves, who defended doggedly and were only breached in unfortunate circumstances when Saka's 70th-minute corner hit the post and bounced in off Johnstone.
The visitors had limited Arsenal to no shots on target in the first half and gave the hosts a scare at the other end when David Raya was forced into a one-on-one save from Hwang Hee-Chan.
Arsenal finally showed some improvement after a wave of second-half substitutions from Mikel Arteta, but were punished for sinking back into their own half after the opener when Matheus Mane's shot was flicked beyond Raya by Arokodare.
The goal sparked an immediate response, however, with Saka, Arsenal's most dangerous player throughout, delivering the cross for a late winner which may prove a significant moment in the title race.
The Gunners celebrated a return to winning ways at the final whistle having been beaten by Aston Villa last weekend but there was a sour note in Ben White being forced off with an injury in the first half.
