A first league double over Chelsea since 1974-75. A first win at Stamford Bridge in any competition since 1979.
Sunday' 4-2 demolition of the Blues was the latest marker of Wolves' undoubted progress under Gary O'Neil, and what an enjoyable one it was for the visitors.
Hat-trick hero Matheus Cunha will grab the headlines for his outstanding contribution, while Pedro Neto once again starred, but it was a complete team performance which ensured Wolves brushed off the disappointment of Thursday's late heartbreak against Manchester United in emphatic fashion.
The manner of the victory was one thing, but the consequences are another.
O'Neil's side are up to 10th, one point and one place above Chelsea after 23 games - and with their sights now firmly fixed on chasing the clubs above them.
