Stones, 32, left Manchester City after 10 years at the club and is now weighing his next move. His availability would allow Arsenal to add an experienced centre-back without paying a transfer fee, an important factor while the club manages other recruitment priorities.
The former England defender also knows Mikel Arteta from their time together at City. That familiarity could reduce the adaptation period, although his recent lack of regular football remains a concern. The report says Stones has started only four matches since November, meaning Arsenal would need to assess both his fitness and his ability to handle a sustained Premier League workload.
Saliba’s importance extends beyond his individual defending. His pace allows Arsenal to hold a high line and defend space behind the midfield, while his partnership with Gabriel has become central to the team’s defensive balance.
If the injury is confirmed as serious, Arsenal may prefer a short-term solution rather than committing to an expensive replacement. Stones would offer experience and versatility, but the club may still need to manage his minutes carefully.
Arsenal’s recruitment plans have also reportedly suffered a blow in attack. Morgan Rogers is said to be close to joining Chelsea from Aston Villa in a deal worth £117 million, leaving Arsenal to revisit a long-term target.
That combination - a major defensive injury and a missed attacking target - could force a more decisive approach in the market. The next medical assessment on Saliba should determine whether Stones remains a contingency or becomes a priority before the transfer window closes.
