Only Daniel Farke and his players will know how they got back into that one.
They barely laid a glove on Chelsea before Lukas Nmecha’s spot-kick and it looked as though their dismal away form – one win on the road this season – would continue.
But their fightback from two goals down was exactly the type of gutsy, spirited display that has epitomised Farke's men in recent weeks.
It didn't come about because of great play or tactical innovation, but through sheer perseverance and refusing to believe that the game was done.
Farke has earned plenty of plaudits since moving to a back three in December, but this was a victory of a different kind.
"We've shown this throughout the season and we've proved we are a proper Premier League side and we want to earn the points to play in this league for longer," Farke told TNT Sports.
"We want to be an established Premier League side in a few years and we are on a good path to achieving that this season."
After West Ham’s draw with Manchester United, Leeds remain six points above the relegation zone.
That gap says more about the Hammers' recent revival in form than it does any lingering fears that Farke's side are still contenders for the drop.
They'll feel that, with 12 matches to play, 10 more points to reach the coveted 40-point mark is more than achievable.
