It perhaps wasn't so shocking that the team able to slow Arsenal's title charge would be led by their former skipper, their former captain. Replacement striker Brobbey netted an stoppage-time equaliser after late goals from Bukayo Saka and Trossard had given Arsenal in the lead following a first-half goal from the home side captain Dan Ballard.
It was a rocky match for the Premier League pace-setters, but Arsenal maintain a seven-point advantage over Manchester City, who are at home the Reds on Sunday, and the hosts, though the Blues could cut the lead to six in the weekend's evening fixture.
Xhaka – who left the Arsenal's home in 2023 looking for what he described as a fresh opportunity – has been exceptional in the promoted side's engine room this season after joining from Bayer Leverkusen, but the 33-year-old's performances on Sunderland's home turf will not have shocked Gunners supporters. The Swiss international revived his Gunners stint under Arteta, who was reluctant to lose him.
Sunderland entered the match with no pressure after achieving the best start to a Premier League campaign by a newly promoted club over 10 games since Hull City in the 2008-09 term. A redirected effort from the midfielder against the Toffees on earlier in the week had boosted them up to fourth place, a position not many local fans would have predicted before a match began given that their side had been almost a decade away from the top flight.
The player's expertise, much of it earned during his lengthy spell at Arsenal, and captaincy have helped the team quickly adjust to Premier League soccer. He appeared to thrive in the physicality of the contest.
The Arsenal manager, once more without Gabriel Jesus, Ødegaard, Kai Havertz, Madueke, Gyökeres and Martinelli, had an initial worry when Merino, playing up front after scoring a brace in midweek's three-nil European win at Slavia Prague, was caught by an elbow from the defender as he attacked a ball into the home box. Merino was able to play on.
Eze almost took advantage of an error from Enzo Le Fée, who was dispossessed on the border of the box, but the attempt soared over the bar.
Wilson Isidor fired off target at the other end before a further long break after a head collision between Le Fée and Timber, who had to carry on with a bandaged head.
A tougher setback was to come next for bruised Arsenal. Sunderland sent a free-kick into the visiting box and the captain held off Rice to drive the ball past David Raya after it was knocked out. It was the opening strike Arsenal had let in since their last visit to the North East in September's end, when they had underlined their title credentials with a late win over Newcastle.
Arsenal had kept a club-record eight consecutive shutouts in all competitions since Nick Woltemade's goal against them at St James' Park.
The Black Cats made sure that it was another uncomfortable visit to the area for the London side, who found themselves under pressure for periods after the interval.
They needed a instance of class, and it came in the 54th minute. Rice took the ball off Le Fée and a smooth attack featuring the winger and the striker ended with Saka beating Roefs at his near post.
Arsenal pressed for a second goal and Le Bris made three changes to his offense – he brought on Brobbey, Chemsdine Talbi and Simon Adingra – midway through the final period.
Another moment of quality was not long in coming. Arsenal worked the play from one flank to the other, and the Belgian, just outside the box, found enough room to lash a right-footed shot into the top left corner.
The keeper had to be alert in the final stages as the hosts pushed for a equalizer, but could not stop an acrobatic shot from the substitute after the ball was headed into the penalty area. The strike was greeted by a huge roar.
Appropriately the defender – like Xhaka another ex-Gunner, this one coming through the youth system – had the final say with a diving block at the toes of Merino in the game's final moment.
