Arsenal have started the season properly, five games, five wins, silverware already banked, and another statement made in Europe. The 1-0 win over Napoli was controlled, mature and, for long spells, one-sided. Martin Odegaard supplied the decisive moment, and Mikel Arteta got more evidence that his side can win in different ways.
Now comes Sunderland away, which looks straightforward on paper and usually never is in practice. The Stadium of Light can turn awkward quickly, Sunderland are unbeaten in three, and Arsenal head there with a familiar problem, defenders in various stages of recovery.
That is the real issue heading into the weekend. Arsenal have quality, depth and momentum, but they are still managing absentees at the back. Here is where things stand with Jurrien Timber, William Saliba and Cristhian Mosquera before the trip to Wearside.
Jurrien Timber closing in on Arsenal return
Timber is the closest of the three to coming back. He has barely featured for Arsenal since damaging his groin against Everton in March. There was the brief sighting off the bench in the Champions League final against Paris Saint-Germain in May, but that comeback did not hold. A setback followed, he missed the World Cup with the Netherlands, and he has yet to play this season.
Still, this is no longer a case of distant optimism. Timber has been back in training for several weeks and travelled with the squad to Naples, even if he was not used. That matters. Players do not make those trips for decoration.
Arteta sounded positive before the Chelsea win and kept it simple, “Jurrien is in really good condition at the moment, he’s been a few weeks on the pitch and has been training with us, so he’s in a really good place.” He added, “We will decide [on his involvement on Sunday] after training [on Saturday].”
That leaves Arsenal with a choice. They can use him at Sunderland if he comes through the final session cleanly, or they can wait and give him minutes against Ipswich in the Carabao Cup. From a squad-management point of view, the second option makes more sense. From a title-race point of view, getting one more senior defender back as early as possible also has its appeal.
Expected return: Sunderland or Ipswich.
William Saliba absence remains Arsenal concern
Saliba is the big one. Arsenal can survive without rotation pieces for a while, they are a different side when one of the best central defenders in Europe is missing for months.
The France international has not played yet this season after aggravating a back problem during France’s run to the World Cup semi-finals in the summer. He avoided surgery, which is good news, but the club have already made it clear this is not a short-term fix.
Arteta’s update was cautious and realistic. “We don’t really know the amount of weeks Wilo [Saliba] is going to be out because it’s about a healing process and everything is a bit different – we know we have to respect certain timings.” He then added, “The progression has been really positive in the last few weeks, but we need to wait and see how that one reacts when we start to put some load into it.”
That tells you plenty. Arsenal are monitoring response, not ticking off a fixed schedule. Back injuries are awkward, recovery is rarely linear, and there is no point pretending otherwise. The best-case scenario looks like late autumn. Anything earlier would be a bonus.
Expected return: likely November or December.
Cristhian Mosquera gives Arteta another decision
Mosquera has had a useful start to life in the Arsenal first-team picture, stepping in alongside Gabriel when Saliba was unavailable. Then came the muscular injury against Aston Villa, which ruled him out of the games against Chelsea and Napoli.
That opened the door for Ezri Konsa, who has taken the opportunity well. He looked assured, defended aggressively and gave Arsenal calm in possession. That means there is no panic around Mosquera, which helps Arteta.
The manager has already indicated the problem is not serious, so this comes down to timing and risk. If Mosquera checks out well in the next assessment, he could be involved at Sunderland. If there is any doubt, Arsenal can hold him back for Ipswich and avoid making a minor issue worse.
Expected return: Sunderland or Ipswich.
Sunderland test comes at awkward time
Arsenal are in good shape overall. Bruno Guimaraes was back on the bench against Napoli after his knock at Villa, Odegaard is sharp, and the team look physically ahead of where many sides are in September. But Sunderland away is the kind of fixture where defensive stability matters more than reputation.
Arteta probably has enough to get through it. What he would prefer, though, is certainty. Timber is close, Mosquera is close, Saliba is not. That is the plain reading of Arsenal’s injury picture before one of the tougher early away trips on the calendar.
