Struggling West Bromwich Albion have caused an extraordinary Premier League shock by winning 5-2 at fourth-placed Chelsea after the Blues had Thiago Silva sent off in the first half at Stamford Bridge.
The experienced Brazilian defender Silva was back in the side following an injury absence for the first time in 10 matches, but was shown the red card in the 29th minute following two bookings.
Christian Pulisic had put Chelsea in front two minutes earlier, only to see Matheus Pereira strike twice in two minutes in first-half stoppage time to give second-bottom West Bromwich, who almost need a miracle to avoid relegation a 2-1 lead at the interval.
Callum Robinson grabbed a third for the Baggies when he swept home a cross from Darnell Furlong in the 63rd minute.
Mason Mount tapped in from close range after good work by Timo Werner to give the Champions League quarter-finalists hope.
But Mbaye Diagne drilled in a low shot to put West Brom 4-2 up and Robinson clipped the ball over goalkeeper Edouard Mendy to complete a surprise scoreline for Sam Allardyce's battlers.
