Matheus Cunha scored a hat-trick as Wolves came from behind to stun Chelsea and replace the Blues in the top half of the Premier League table.
Cole Palmer gave Mauricio Pochettino’s hosts a 19th-minute lead when he calmly slotted past Jose Sa following Moises Caicedo’s defence-splitting pass.
But Wolves levelled less than three minutes later when Cunha’s shot took a significant deflection off Thiago Silva and wrong-footed Djordje Petrovic.
The turnaround was complete shortly before the break, courtesy of another deflected shot, as Rayan Ait-Nouri met Pedro Neto’s cutback and sent the ball in off Axel Disasi.
The home supporters greeted the half-time whistle with boos but Chelsea were unable to produce a fightback of their own, instead falling two goals behind when the electric Neto beat Silva for pace and picked out Cunha for his second.
The Brazilian then completed his hat-trick from the penalty spot after being brought down by Malo Gusto, sending Petrovic the wrong way with eight minutes remaining to put the result beyond doubt before Silva headed in a late consolation.
Wolves’ thoroughly deserved victory moved Gary O’Neil’s side up to 10th, one point and one place above Chelsea after 23 games.
With the added incentive that victory at Stamford Bridge would lift them above Chelsea, Wolves brushed off the disappointment of losing out to a 97th-minute winner in their seven-goal midweek thriller against Manchester United to reach the top half of the table for the first time under O’Neil.
Wolves had not completed a league double over Chelsea since 1974-75, nor had they managed to win at Stamford Bridge in any competition since 1979.
That they brought an end to both of those waits on Sunday, in the manner they did, was the latest evidence of the terrific job O’Neil continues to do in his first season in charge.
