The William Saliba conundrum: How Arsenal should handle the return of their star defender

When it was first announced that William Saliba would face an extended spell on the sidelines thanks to a back injury which had worsened during France’s World Cup run, early reports suggested that he could easily be out until December, perhaps even longer. Potentially season-ending surgery was mooted as a treatment plan. Just a few days into November, however, he’s back.

His remarkable recovery is great news for Mikel Arteta and Arsenal, but also gives the head coach a serious headache: Ezri Konsa, the man signed for £55m to stand in for Saliba, has been outstanding and has played a key role in making the Gunners’ defence the best in the Premier League.

So how does Arteta juggle his luxurious wealth of options? Could Konsa move to full-back? And could Saliba’s premature comeback actually end up being a bad thing for Arsenal?

William Saliba is back for Arsenal – but that might not make life easier

Saliba made it as far as the matchday squad for the first time in the 2026/27 season on Wednesday, when he sat on the bench during the 2-1 Champions League win over Slavia Praha. The Frenchman might not have played, but his mere presence in the dugout was exciting enough for most Arsenal fans.

Outstanding for most of last season when the Gunners won the Premier League title for the first time in over two decades, Saliba’s loss was expected to be a serious blow to a defence which was the best in the division last year and which conceded only 27 goals. As it turned out, however, his absence was much less of an issue than some observers might have envisaged.

Arsenal have conceded just five in their first nine games, kept six clean sheets including a potentially crucial one at Anfield, and their defence has been even better as a whole, at least based on the raw numbers. Konsa hasn’t just been an expensive stopgap. He’s quickly become a critical part of a unit which has actually improved in Saliba’s absence.

Konsa has matched Saliba’s statistical output in almost every key area since establishing himself as Arsenal’s starter alongside Gabriel Magalhães, and there are some areas in which he’s arguably even better – not least in one-on-one situations, in which he has been titanic since the summer.

Of all the defenders in the Premier League to have featured in at least five games this season, only 10 have won ground duels more often than Konsa, and only three different players have won a higher percentage of such battles. Some of the best technicians in the world have been trying to work the ball past him and Konsa has been exceptionally good at shutting them down.

Few managers would drop either of Arsenal’s current centre-backs given their current form, but Saliba needs to be given minutes from somewhere. How Arteta intends to handle a tricky situation remains unclear.

We may get to find out this weekend, when Arsenal welcome Hull City to the Emirates, although it’s unlikely that Saliba starts immediately. A gradual introduction is more probable, which would not only help to ensure that he works his way back to match fitness without undue risks but would also provide Arteta with a drip-feed of date to assess how best he should reshuffle his pack.

A slight complication could be that Konsa picked up a knock in Prague on Wednesday. The former Aston Villa defender appeared to be slightly hobbled when he came off around the hour mark, and his manager later confirmed that he “had some issues.” There’s a chance that Konsa can’t even fight for his place on Saturday, although he couldn’t make his case much more compelling than he already has.

Will Saliba take Konsa’s place – and should he?

As excellent as Konsa has been, however, it will be hard for Arteta to resist the temptation to renew the hugely successful partnership that Gabriel and Saliba have put together over the past four years. The debate is whether or not he actually should.

Champions League matches will afford some opportunities for rotation over the coming months, but it would be out of character for Arteta not to settle on a primary defensive partnership before long. Once he is convinced that Saliba is fully fit and ready for a 90-minute shift, he will have a very consequential decision to make.

Based on the raw data, there probably wouldn’t be a huge difference in terms of defensive quality whichever player starts at centre-back. Both make roughly the same number of blocks, tackles, and clearances, force as many turnovers, and while Konsa does have the edge in one-on-one scenarios, Saliba can counter that with the quality of his distribution.

While Konsa is an accurate and economical passer, he lacks Saliba’s range and plays many fewer direct downfield balls. Putting Saliba back into the mix should allow Arsenal to set up more quick attacks, and given that they have carried less of a goal threat than some of the other teams towards the top of the Premier League table – and have played fewer accurate long balls than any other team in the division - adding more capacity to move possession forward at speed might help to address the team’s weaknesses too.

Konsa can, of course, play at right-back as well, and his relatively conservative approach to the full-back role meshes well with Arteta’s system. But that would only push the decision to a different part of the pitch, with Jurriën Timber and Ben White already competing for minutes in that position. Arteta has, in any case, already told the media that he sees centre-half as Konsa’s natural position.

Saliba’s return also serves to push Cristhian Mosquera and Piero Hincapié even further down the pecking order, setting up potential frustrations down the line for two more players in whom Arsenal have invested significant time and resources. That is a can that can be kicked down the road a little way, but it’s another factor that Arteta must consider as he works out how to rebuild his defence.

There probably is no correct solution to a puzzle that reflects an embarrassment of defensive riches at the Emirates. If Arteta wants more quick passes down the pitch, Saliba has to come back in, and most likely will before long. If he wants to make sure that Konsa remains involved, he may have to shuffle him to right-back and step on Timber’s toes.

Whatever solution Arteta comes up with, there will be at least one rather unlucky loser. Somebody who deserves to be starting will be stuck on the bench for long periods. At least until the next injury strikes. Then it will all look like a rather pleasant problem to have. It may be a headache, but it’s one that every team would be willing to cope with if they could.
