During his time on the south coast, Arrizabalaga regained his form after a challenging period at Chelsea. Arsenal is looking to add a reliable backup goalkeeper to their squad, and Arrizabalaga's experience and skills may make him an attractive option.
Kepa has a release clause in his Chelsea contract worth £5 million, and the club is looking to offload several players this summer. This could make it easier for Arsenal to secure his signing.
