Chelsea put a smile back on Maurizio Sarri's face with a crucial 2-0 win over Tottenham that secured a stay of execution for their troubled manager after Kepa Arrizabalaga was dropped following his Wembley mutiny.

Pedro's second half strike and a farcical own goal from Kieran Trippier were a much-needed boost for Sarri as the Chelsea manager fights to avoid the sack following a turbulent first season in charge.

Sarri's standing had been severely undermined by Kepa after the rebellious keeper sparked an astonishing meltdown from the Italian when he refused to be substituted during Sunday's League Cup final.

Sarri was furious when Kepa ignored his decision to take him off after he required treatment for cramp in the closing stages of their penalty shoot-out defeat to Manchester City.

Kepa apologised for his behaviour, but the 24-year-old was punished with a fine of one week's wages before Sarri attempted to regain control of his squad by selecting Argentine veteran Willy Caballero in his place at Stamford Bridge.

Caballero kept a confident clean-sheet while Kepa languished on the bench and Chelsea produced a committed display that suggested Sarri's players still back their beleaguered boss.

With Arsenal and Manchester United both winning on Wednesday, Chelsea remain in sixth place, three points outside the top four but there is now a little hope for Sarri after a difficult period.
