Arsenal's perfect Premier League start: What has changed since winning the title?

After winning the Premier League in 2025/26, Arsenal have started their title defence in convincing fashion. Mikel Arteta's side opened the new campaign with four consecutive league victories, showing that last season's success has not reduced their intensity.

The key question is not simply why Arsenal are winning again, but what has changed since they became champions. The answer appears to be a combination of continuity, greater squad depth, and improved confidence in difficult moments.

A Strong Foundation Is Still There Arsenal did not need a complete rebuild during the summer. Their title-winning campaign was based on a clear tactical identity, defensive organisation, and a midfield capable of controlling matches.

Several strengths have carried directly into the new season: a well-organised defensive structure; experience in high-pressure matches; strong control of possession; tactical discipline; confidence gained from winning the title. The most important difference may be psychological.

Arsenal are no longer a team trying to prove that they can become champions. They now know that they can win the league.

That experience can help when matches become difficult. More Quality in Midfield One of the most important additions was Bruno Guimarães.

His arrival gives Arteta another high-level option in central midfield. Guimarães can contribute defensively, carry the ball forward, and help Arsenal maintain control when opponents press aggressively.

His early influence was visible in the victory against Sunderland. After David Raya saved a penalty, Guimarães scored shortly afterwards to put Arsenal in front.

That sequence demonstrated something important about the current team. Arsenal can survive a dangerous moment and immediately respond at the other end of the pitch.
