Pedro Neto was Wolves' hero in second-half stoppage time as the Portugal international sealed a 2-1 comeback win over Chelsea at Molineux on Wednesday (AEST).
Frank Lampard's men went into the match the possibility of going top temporarily, but Wolves showed admirable character to come from behind to secure a fine victory against the odds.
Kurt Zouma went closest to breaking the deadlock late in the first half as he hit the frame of the goal, before Olivier Giroud did convert his seventh goal in as many games with 49 minutes on the clock.
Wolves were unperturbed, however, as Daniel Podence – a nuisance to Chelsea throughout – got himself a deserved goal in the 66th minute to restore parity.
Chelsea had seemingly ensured a share of the spoils when Wolves had a penalty award overturned, Neto deemed to have simulated contact in the area, but the winger ultimately had the final say in the fifth minute of stoppage time.
A largely drab first half belied the drama that was to unfold in the second period, with the only moment of true excitement occurring right before the interval when Zouma sent a towering header onto the crossbar.
Wolves were not so lucky soon after the restart, however.
Ben Chilwell's low delivery from the left was met by Giroud at the near post and Rui Patricio could not quite keep an instinctive finish out of his bottom-right corner.
Fabio Silva then had what would have been his first Premier League goal disallowed for offside, though Wolves did draw level in the 66th minute.
Chelsea failed to deal with the tricky Podence, and his lovely effort took a slight deflection off a defender on its way into the back of the net.
The hosts then seemingly had the chance to clinch victory taken away from them when a VAR review corrected the referee's initial error of pointing to the spot when Neto went to ground under pressure from Reece James.
But all eyes were on the Wolves man for the right reasons at the end, as Neto latched onto Vitinha's pass on the counter, ran at Zouma and fired a pinpoint finish into the bottom-right corner.
