The Blues made the 23-year-old the most expensive goalkeeper in the world following his £71m move to Chelsea FC from the La Liga outfit on Thursday.
Kepa completed a deadline day move to the west London side as his transfer eclipsed the £67m fee that Liverpool FC paid for AS Roma’s Alisson Becker.
The Spain international will be tasked with replacing Thibaut Courtois after the Belgium international completed a £31m move to Real Madrid on Thursday.
Kepa turned down the chance to move to the Champions League holders back in January before completing a move to the English capital eight months later.
The new Chelsea FC signing is still waiting to win his first major trophy, having made a mere 53 appearances for the Bilbao first-team.
Speaking to the club’s website about his ambitions at the Stamford Bridge side, Kepa said:
“All clubs needs to fight to win titles and what all players want is to win. So what I would like is to win more titles for the club.
“This is what I aspire to do. I would like to be remembered at this club, when I leave years down the line, as a goalkeeper that has helped the club win a lot of titles and gone down in history.”
Chelsea FC appointed Italian head Maurizio Sarri as their new manager following Antonio Conte’s dismissal last month.
The Blues have signed Napoli midfielder Jorginho, Real Madrid star Mateo Kovacic and veteran goalkeeper Rob Green this summer.
