Don't think we have bridged the gap to Arsenal. They are closer to forming a league-winning team than we are. Signing players like Zubimendi, Eze shows they are a serious tactical project and Arteta is obsessed with building a team that has solutions to break down low-blocks.
As much as Maresca has found a way to play now, we don't have the same obsession as Arsenal if we are competing for Gittens/Garnacho in the same area of the pitch where Arsenal have signed Eze.
