Chelsea goalkeeper Kepa Arrizabalaga has reportedly completed a shock move to London rivals Arsenal.

The Gunners have activated Kepa's £5 million release clause to sign him as a backup option to first-choice goalkeeper David Raya.

The 30-year-old becomes Mikel Arteta's second signing of the summer, following the arrival of Martin Zubimendi.

Kepa spent last season on loan at Bournemouth, where he enjoyed an impressive campaign with the Cherries.

The move was announced by transfer expert Fabrizio Romano on X:

“Kepa to Arsenal, here we go!

Deal done for the Spanish goalkeeper to join #AFC as new backup for David Raya.

Arsenal activate £5m clause from Chelsea and all documents are now sealed.

One more addition for Arteta after Martin Zubimendi.”
