Arsenal have completed their first major signing of the 2025/26 summer transfer window with Martin Zubimendi finally landing from Real Sociedad. Mikel Arteta is pushing to launch a renewed Premier League title challenge in the coming months with Zubimendi highlighted as a key target since the start of 2025.
