The Champions League trophy is the only missing piece of the puzzle

Mikel Arteta has finally cracked the Premier League code. After years of finishing as the bridesmaid, Arsenal finished at the top of the pile this season, and the Emirates is rightfully losing its collective mind. But before the confetti is even swept off the pitch, the narrative has shifted immediately to the Champions League. Arteta is out here telling anyone with a microphone that the club’s ambition has now outgrown the domestic league.

It is the kind of talk that makes the hairs on a fan’s neck stand up until you look at the track record in Europe. Arsenal has a history of choking in this competition that dates back to the Arsène Wenger years when every knockout stage felt like a funeral. We watched them get dismantled by Bayern Munich year after year with a level of consistency that would be impressive if it wasn't so depressing.

The squad depth problem is staring everyone in the face

Arteta wants Champions League glory, but he is currently juggling a roster that looks a bit thin once you get past the starting eleven. You cannot compete with the bottomless coffers of Manchester City or the tactical wizardry of Carlo Ancelotti at Real Madrid if your backup winger is a guy who hasn't seen a full ninety minutes since the group stage. If they are serious, this summer window needs to be aggressive.

The club is already making noise about massive moves, including a 104 million bid for Julian Alvarez which would be the biggest transfer statement in Premier League history. Spending that kind of coin on a player who has already proven he can find the net in a high-pressure environment is the exact type of move you make when you are aiming for Ol' Big Ears. However, spending big is not a magic shield against tactical fatigue.

Tactical rigidity or a winning formula?

One of the biggest concerns with Arteta is his obsession with specific tactical systems. In the Premier League, you can overwhelm teams with that rigid high press, but in the Champions League, you often need to be a chameleon. Think about the way the 2005 Liverpool side lucked into a trophy through chaos or how Chelsea played the ultimate spoiler in 2012 by just sitting in a low block and praying for a miracle.

Arteta is miles better than the managers we saw post-Wenger, but there is still a stubbornness there. When the game slows down in April and the knockout stages turn into a chess match, he needs to show he has a Plan B that isn't just bringing on a defender to grind out a draw. Taking the league title is a massive feat, but the Champions League is a completely different animal that eats tactical purists for breakfast.

The weight of history is still dragging behind them

Let’s be real about the baggage. Arsenal hasn't lifted a continental trophy that matters in decades, and until they prove they can handle the pressure of an away leg at the Allianz Arena or the Bernabéu, the doubters will keep their seats. They have all the data, the analytics guys are working overtime, and the recruitment team is firing on all cylinders.

Still, the transition from a top-four contender to a European heavyweight is where most clubs break their necks. Manchester City took ages to figure out how to navigate the final stages of the tournament despite having the best manager on the planet. If Arteta wants to be held in that same breath, he needs to stop talking about ambition and start managing the fatigue that killed their squad toward the end of their last campaign.

The verdict before the summer even turns

We are just weeks away from the 2026 World Cup disruption, meaning the squad is going to be battered before the next season even hits its stride. If Arteta is truly looking at European dominance, he needs to manage his players like they are made of glass throughout the autumn schedule. We saw the team run out of steam in the final weeks of the league title race, winning the trophy because they had just enough cushion to coast over the line.

Champions League knockouts do not allow for coasting. You lose one half in Eindhoven or Turin, and you are spending the second leg of the tie chasing a ghost. I love the arrogance of the statement, but let’s see if the squad composition matches the manager's words. I will put my money where my mouth is when I see them actually handle a heavy fixture list without dropping points to a bottom-three side in the middle of a quarter-final week.
