Arsenal are actively scouting for a new centre‑back this summer after the club received unsettling news that William Saliba will be sidelined for an extended period. The French defender suffered a back injury during France’s World Cup semi‑final loss to Spain, and although he has escaped the need for surgery, the 25‑year‑old now faces a lengthy rehabilitation programme that could keep him out of action for several months. In response, the Gunners have placed their attention on two English internationals who could potentially fill the void: John Stones and Ezri Konsa. Both players have been linked with a move to North London, and each brings a distinct set of attributes that could complement Mikel Arteta’s defensive plans.

John Stones, who has just become a free agent after his contract with Manchester City expired last month, is an experienced centre‑back with a decade‑long pedigree at the Etihad. During his time in Manchester, Stones helped the club capture 17 trophies, including six Premier League titles, and he featured regularly for England at the World Cup, making five appearances. His familiarity with Arteta is another compelling factor – the two worked together for three seasons when Arteta served as Pep Guardiola’s assistant at City.

Arteta has spoken publicly about his admiration for Stones, recalling how they followed his progress before signing him at City and noting the defender’s blend of composure, aerial ability and ball‑playing skills. Stones’ contract situation makes him an especially attractive target: he is available on a free transfer, meaning Arsenal would not need to meet a transfer fee, only negotiate personal terms and a signing‑on bonus.

This could provide a short‑term solution while Saliba recovers, and his recent World Cup performances suggest he has returned to full fitness. However, his injury record raises some caution.

In the 2022‑23 season he managed just 439 Premier League minutes, and the previous campaign saw a similar limited involvement due to thigh, calf and other muscular problems. Over his ten‑year spell at City, Stones never featured in more than 59 percent of the league minutes, indicating a pattern of recurring fitness issues that Arsenal will need to weigh against his experience and leadership.

Ezri Konsa, on the other hand, offers a contrasting profile. The 28‑year‑old Aston Villa centre‑back is four years younger than Stones and still has two years left on his contract with Villa. Arsenal have reportedly begun preliminary talks about a possible deal, but Villa’s valuation – estimated at around £60 million – creates a significant financial gap that could prove difficult to bridge. Konsa’s durability is a major selling point; he has started at least 33 Premier League games in each of the last five seasons and has not suffered any major injuries that kept him out for extended periods.

Konsa’s style mirrors many of the qualities Arteta values. He is comfortable on the ball, capable of playing out from the back under pressure, and primarily operates as a right‑sided centre‑back – the same position Saliba occupies.

During the World Cup, Konsa also demonstrated versatility by covering at right‑back, a flexibility that could be useful given Arsenal’s occasional need for cover in that area. Statistically, he shines in one‑on‑one situations: Opta recorded him as having the highest ground‑duel success rate of any outfield player in the Premier League last season, winning 73 percent of his challenges. His physicality, aerial prowess and tenacity make him a formidable opponent in defensive duels. Choosing between Stones and Konsa involves balancing immediate cost against long‑term value.

Stones would arrive on a free transfer, but his injury history and advancing age (he will turn 31 this summer) may limit his impact to a short‑term stop‑gap. Konsa, while demanding a substantial transfer fee, brings youth, consistency and a proven injury‑free record, potentially offering a more sustainable solution for Arsenal’s back line. Moreover, Konsa’s market value reflects his standing as one of the Premier League’s top defenders in direct confrontations, a reputation that could justify the investment if Arsenal are looking to build a defensive core for the next several seasons. Arsenal’s defensive roster already includes several options.

The club secured the permanent signing of Piero Hincapié after a successful loan spell from Bayer Leverkusen, and they also have Gabriel, Riccardo Calafiori, Cristhian Mosquera, Jurrien Timber and Ben White competing for centre‑back spots. White has recently returned to training after a knee injury sustained in May, and Timber has indicated he hopes to be back soon following a groin problem. This depth suggests that Arteta is not forced into a single solution but rather can assess the best fit based on form, fitness and financial considerations. Beyond the immediate transfer speculation, Arsenal have been exploring analytical tools to identify players with similar profiles to Saliba.

Using Twenty3’s player similarity algorithm, the club discovered that the most comparable defenders across Europe are Inter’s Manuel Akanji, Nice’s Kojo Peprah Oppong and Como’s Jacobo Ramon, each scoring around 97 percent similarity. Within the Premier League, only Chelsea’s Trevoh Chalobah and Manchester City’s Ruben Dias rank in the top ten, with similarity scores of 94 percent. Neither Stones nor Konsa appear among the ten most stylistically similar players to Saliba, though Konsa narrowly misses the cut, landing at twelfth place. In summary, Arsenal’s pursuit of John Stones and Ezri Konsa reflects a strategic response to Saliba’s injury woes.

Stones offers a wealth of experience and a cost‑effective free‑transfer deal, albeit with lingering concerns over his fitness record. Konsa provides durability, versatility and impressive defensive statistics, but at a considerably higher price tag that could strain Arsenal’s budget.

As the summer transfer window progresses, Artetta and his recruitment team will need to weigh these factors carefully, balancing short‑term coverage with the long‑term stability of the Gunners’ defensive line. The final decision will likely hinge on the club’s financial flexibility, Saliba’s projected recovery timeline, and the broader vision Arteta holds for Arsenal’s back‑four in the coming seasons.
