Chelsea signed Kepa Arrizabalaga from Athletic Bilbao for a club record £71m in August 2018Goalkeeper Kepa Arrizabalaga has been fined a week's wages and apologised for refusing to be substituted during Chelsea's Carabao Cup final defeat by Manchester City on Sunday. The Spaniard refused to be replaced by Willy Caballero at Wembley. "Although there was a misunderstanding, on reflection, I made a big mistake with how I handled the situation," Kepa said in a Chelsea statement. Sarri, who reacted angrily when Kepa refused to leave the field towards the end of extra time, also said the incident had been "a misunderstanding". Kepa, the club's record £71m signing, defied Sarri's attempt to substitute him for Caballero before Manchester City won on penalties.
