The Spain international is Leverkusen's second arrival during the close season, along with Jeanuel Belocian, who will join the club from Ligue 1 side Rennes on 1 July.

Garcia played a key role in the middle of the park during a memorable 2023-2024 campaign for Girona, with three goals and six assists in 37 appearances as it finished third in LaLiga and qualified for the Champions League for the first time.

The 26 year-old will link up with compatriot Xabi Alonso, who oversaw an unbeaten domestic season as Leverkusen landed the first Bundesliga title in its history.

Die Werkself also captured the DFB-Pokal and were runners-up to Atalanta in the Europa League, and Garcia hopes he can help the club build on that success.

"I'm very happy to join this big club," he told Leverkusen's official website.

"Like football fans in the whole of Europe, I have admired Bayer Leverkusen for their exceptional achievements in the season just gone. That's why I wanted to join this club, to do big things.

"I've been thrilled that a club like this has done so much to get me. Now, I definitely want to fulfil all the expectations of myself, and make my contribution to this team and the club in continuing to be successful."
