Mikel Arteta's Right-Back Dilemma: Managing Arsenal's Defensive Depth

Mikel Arteta is walking a tightrope on the right side of his defence.

Ben White’s groin injury against Sunderland has handed Arsenal a fresh headache in a position already pushed to its physical limit. The defender failed to emerge for the second half at the Stadium of Light, a precaution that instantly sharpened focus on the Gunners’ right‑back depth.

This comes just as White had rediscovered his stride. After a knee injury wrecked his World Cup hopes in May, he had opened the new campaign in sharp, aggressive form. He even shrugged off a knock against Napoli in the Champions League. But this latest issue, coming so soon after that, leaves Arsenal juggling another delicate fitness call.

A brutal role in a brutal schedule

On Wearside, it was Jurrien Timber who stepped in for his first minutes of the season, himself only just back from a groin problem. One defender out, another pushed straight into the fire. That is the reality of the modern full-back.

The position has changed. It is no longer about quietly locking down a flank. At Arsenal, it is a relentless shuttle run. Arteta demands overlapping and underlapping runs, constant recovery sprints, repeated accelerations into the same strip of grass, over and over again.

Injury performance analyst Stephen Smith of Kitman Labs underlined just how punishing that is.

“Full-back is certainly one of the most demanding positions on the field and the data backs it up,” he told Metro. “The honest picture is demand for a full-back isn’t about total mileage, it is about the type of running – repeated, explosive sprints up and down the same channel.”

That description could have been written with White and Timber in mind.

Depth on one side, a balancing act on the other

Across the squad, Arsenal are not short of options in wide defensive areas. On the left, Riccardo Calafiori, Piero Hincapie and Myles Lewis-Skelly give Arteta flexibility and freshness. The right is a different story. There, the load is concentrated, the margin for error thinner.

White’s omission from the Carabao Cup win over Ipswich underlined the concern. With the England international unavailable, Martin Zubimendi had to shift across to right-back. Timber, still being carefully managed after his ACL nightmare last season, was also rested. Arteta later confirmed the Dutchman had suffered no new setback, but the caution spoke volumes.

Smith’s warning on recovery timelines adds another layer.

“Even a mild groin or adductor strain typically needs a week or two of managed loading before a player is even back to full training intensity,” he said.

In other words, rush this and you pay later.

Brighton, then a breather

Next up is Brighton on Saturday afternoon, a meeting with White’s former club that arrives at an awkward moment. He could yet feature, depending on how he responds in the days before the game. Arsenal know they cannot afford to gamble recklessly, not with a three-week international break looming.

That pause might be the real prize. Three weeks of controlled work at London Colney. Three weeks to build White and Timber back towards full throttle, rather than lurching from game to game on the edge of another breakdown.

For a side with title ambitions, this is not just about who starts at right-back against Brighton. It is about who is still sprinting down that flank in March and April. Arteta’s challenge now is simple and unforgiving: rotate smartly, manage the load, and keep his two elite right-backs on the pitch when the season reaches its brutal peak.
