Arsenal's Squad Depth: A Challenge for Mikel Arteta

Mikel Arteta walked away from Arsenal’s opener against Coventry City with a 3-0 win, three points, and barely a bead of sweat on his players. He also walked away with a headache.

Arsenal cruised. They never needed to hit top speed to swat aside Frank Lampard’s side, who were outclassed from the first whistle. It was so one-sided that the conversation barely touched on the three heavyweights missing through injury: Bruno Guimaraes, William Saliba and Jurrien Timber.

That silence said plenty. This squad is stacked.

A squad that’s almost too strong

Arsenal now boast one of the deepest groups in Europe. Arteta can call on two high-level options in almost every position, and that sort of depth usually wins titles. It cushions injuries, sustains intensity, and keeps standards high on the training ground.

But it also brings something else: tension.

The Premier League allows only eight outfield players on the bench. That means, every weekend, some big names don’t just miss the XI – they miss the squad entirely. Not because they’ve underperformed. Not because they’ve slacked off. Simply because there’s no room.

Gary Neville, watching on for Sky Sports, believes that’s where Arteta’s real challenge lies this season.

“He has created a real problem for himself,” Neville said, pointing to the sheer volume of quality at Arteta’s disposal. He recalled Sir Alex Ferguson’s old admission at Manchester United: the hardest part of the job was not picking the team, but looking good professionals in the eye and telling them they weren’t involved at all.

Arteta now faces the same reality.

The Ferguson problem, North London version

Neville laid it out clearly on air: “Sir Alex Ferguson used to say, the hardest thing was leaving those players out every week. He’s going to have to do the same. I said to him off camera, what a squad he has built here. If he puts another forward into that, (puffs his cheeks).”

The win over Coventry showed exactly what he meant. Arteta named a powerful squad and still had three injured stars – Guimaraes, Saliba and Timber – watching on. Ezri Konsa is also expected to come into the fold. When all four are fit, someone who featured in that comfortable 3-0 will be watching from home.

Not from the bench. From the sofa.

These are not fringe players in the traditional sense. They are internationals, title-chasers, players who could walk into most Premier League starting line-ups. Leaving them out of a matchday squad will sting.

That is why Arteta has pushed for the Premier League to increase the number of players allowed in a squad on matchdays. He wants more flexibility, more room to reward the work done from Monday to Friday. So far, the decision-makers show no sign of bending.

An unavoidable flashpoint

Neville’s warning cuts to the core of Arsenal’s looming issue. This is not about tactics, formations, or even transfer strategy. It’s about ego, trust and man-management across a long, gruelling season.

Arteta can rotate. He can explain. He can promise minutes across four competitions. But as long as the rules stay as they are, some very good footballers will be told, “You’re not involved today,” regardless of how well they train or how professional they are.

There is only one clean way out of that bind: trim the numbers. Sell a few players before the window shuts and ease the logjam.

For now, though, Arsenal look powerful, ruthless and deep. The champions have stood up. The question is whether Arteta can keep everyone standing with him once the reality of those weekly omissions begins to bite.
