Arsenal open the Premier League season at home to Coventry City on Friday 21 August at 20:00. The summer transfer window closes on 1 September. The champions will play at least three league matches before their squad is final.
Mikel Arteta said as much after Sunday's 3-0 Community Shield win over Manchester City. "We know that there are certain areas that, through injuries, we are weaker and we need to strengthen," he said. "We are trying to do that, we've been trying to do that for weeks, so only the right opportunity and the club is able to do it. We will do it."
That is a manager who just won a trophy telling you the squad is not finished.
What Arsenal still need
The injuries Arteta mentioned are William Saliba and Jurrien Timber, both out for the start of the season. Arsenal played City without them and kept a clean sheet. That does not mean they do not need cover. It means they have 18 players who were good enough on Sunday.
The attacking links have been louder. Julian Alvarez reportedly refused a move to Arsenal and wants Barcelona, according to beIN Sports via Football.London. Victor Osimhen is not for sale "under any circumstances," per Galatasaray president Dursun Ozbek, despite Arsenal's interest. Arteta confirmed Viktor Gyokeres will stay.
Arsenal signed Bruno Guimaraes for £75m, Christos Tzolis for £34m, and Piero Hincapie for £34.5m. They let Leandro Trossard go to Besiktas, Jakub Kiwior to Porto, and Christian Norgaard to Everton. The net result is a squad that just beat City 3-0 and still has Arteta talking about strengthening.
What Arteta actually said about the squad
After the Shield, Arteta was asked about the matchday squad rules that left Gabriel Martinelli and Gabriel Jesus out. "Really sad to not have their availability," he said. "I have been fighting with the Premier League to extend them and to accommodate more players in the squad. They deserve to be in the squad. Hopefully we can change that rule."
On departures, he was more direct in a BBC Sport press conference: "We have set out some possibilities we can explore if the right possibilities come across but so far with the numbers that we have, we are happy. But obviously we have to accept that there are some players that will probably have to move."
Arsenal have five midfielders for two seats. They have a 19-year-old who just started the Community Shield after a week of Chelsea and Manchester United links. They have a striker who scored on Sunday and another one injured. The window is open. Arteta knows it. Friday is the first sheet that counts.
What Friday actually tests
Coventry are not City. They are Championship champions under Frank Lampard, opening their Premier League season away at the champions. The opening night preview already covered rest defence, set-pieces, and the five-into-two midfield problem.
Friday tests whether Sunday's 3-0 was a marker or a memory. Lewis-Skelly started against City after the transfer noise. Rice came on at half-time. Tzolis assisted twice on his debut. Guimaraes started. That XI was good enough to beat City. It has to be good enough to start a title defence against a promoted side.
The window running to 1 September means Friday's squad is not necessarily September's squad. If Arsenal sign a striker or lose a midfielder before deadline day, the team that opens the season will not be the team that finishes it. That is the calendar, and every club lives with it.
What to watch before the window shuts
Watch Friday's team sheet. If Lewis-Skelly starts again, the Chelsea enquiry is still noise. If Rice comes straight back in, the five-into-two problem has a default answer. If Tzolis keeps his place ahead of a fit-again Saka or Martinelli, the debut was a promotion, not a cameo.
Watch the striker links. Alvarez said no. Osimhen is not for sale. Arsenal need goals from somewhere if Jesus is injured and Gyokeres is the only other option. The window has 13 days left. Arteta has already said they are trying.
Watch who leaves. Arteta said certain players probably have to move. If that happens after Friday, the squad that starts the season is not the squad that defends the title. The Shield was a marker. The league starts now. The shopping list is still out.
