The 23-year-old Spanish international goalkeeper arrives ahead of the new Premier League season having signed a seven-year contract at Stamford Bridge.

Kepa, who has played over 100 career league games, has solid experience at the highest level having made more than 50 appearances in La Liga, his quality earning him a call-up to the Spain squad for this summer’s World Cup in Russia.

Upon completing his move to Chelsea, he said: ‘It’s a very important decision for me, for my career, and also for my personal life.

'So many things attracted me to the club, all the titles the club has won, the other players, the city, the English Premier League. It’s an accumulation of things, and I am very glad Chelsea has decided to trust me and to take me in as well.’
