Crystal Palace took advantage of 10-man West Bromwich Albion to thrash them 5-1 away.
It was the first time Palace have scored five goals on the road in the Premier League.
Wilfried Zaha, back after a two-game absence after testing positive for Covid-19, was instrumental in the eighth-minute opener.
He latched onto Luka Milivojevic’s quick free-kick to send in a dangerous cross that was turned into his own net by Darnell Furlong.
West Brom drew level on the half-hour mark after Conor Gallagher drove a low strike into the bottom corner.
The game’s turning point came four minutes later when the Baggies’ Matheus Pereira was shown a red card after he made contact with his studs on Patrick van Aanholt’s chest while on the ground. Referee Paul Tierney made his decision after consulting the pitch-side monitor.
Ten minutes after the break, Zaha restored Palace’s lead with a powerful strike off James McArthur’s feed.
Christian Benteke nabbed a rare goal to make it 3-1 with a low header from Patrick van Aanholt’s cut-back in the 55th minute.
Zaha fired home from close range for his second goal on 68 minutes after a driving run into the box from Eberechi Eze.
Then Benteke added another himself and Palace’s fifth of the day with a nice turn and finish inside the area.
