Premier League leaders Arsenal led 2-0 and looked set to secure a comfortable away victory against Wolves, who have long languished at the bottom of the table.
But in the 61st minute the home team reduced the deficit through Hugo Bueno. In the 94th minute substitute Tom Edozie fired a shot that, via Arsenal defender Riccardo Calafiori, found the net.
The match ended 2–2 and Arsenal are now only five points ahead Manchester City, who have one game in hand.
