Arsenal are reportedly turning their attention to two centre‑backs – John Stones and Ezri Konsa – as they search for a replacement for the injured William Saliba this summer. Saliba, who escaped surgery after aggravating a back problem in France’s World Cup semi‑final loss to Spain, now faces an extended rehabilitation period, leaving the Gunners with a serious gap at the heart of their defence. John Stones, who became a free agent after his contract with Manchester City expired last month, is among the names being floated. Sky Sports News has indicated that Chelsea are also monitoring the England international, but Arsenal’s familiarity with Stones could give them an edge.

The defender spent three years working under Mikel Arteta while Arteta was Pep Guardiola’s assistant at City, and the two share a professional relationship that dates back to that period. Stones brings a decade of top‑flight experience, having collected 17 trophies at the Etihad, including six Premier League titles. Arteta has spoken publicly about his admiration for the player, recalling how he tracked Stones before Arsenal signed him in 2020.

"John is a player I really like," Arteta said. "We followed him before we signed him when I was at City. I worked with him for many years. I know him well and when I look at centre‑backs, he has many attributes that I like." The fact that Stones is available on a free transfer makes him an attractive short‑term solution, especially after he proved his fitness during the World Cup, where he featured in five matches for England.

However, his injury record raises concerns. Over the past two seasons he managed just 439 Premier League minutes in 2022‑23 and 547 minutes the season before, hampered by thigh, calf and other muscular problems.

In his ten years at City, he never featured in more than 59 % of the league minutes, suggesting a pattern of recurring setbacks. Ezri Konsa offers a different profile. The 28‑year‑old Aston Villa defender, who also played alongside Stones for England at the World Cup, still has two years left on his contract. While Arsenal have reportedly begun discussions on a possible fee, Villa’s valuation – around £60 million – creates a substantial gap between the clubs.

Konsa is praised for his durability; he has started at least 33 Premier League games in each of the last five seasons and has avoided any major injury layoffs. Like Stones, Konsa is comfortable on the ball and can cope with pressure from opponents. Primarily deployed as a right‑sided centre‑back – the same role Saliba occupies – he also demonstrated versatility by covering at right‑back during the World Cup. His physical attributes are noteworthy: Opta data revealed that he recorded the highest ground‑duel success rate of any outfield player in the Premier League last season, winning 73 % of his contests.

This combative edge aligns well with Arteta’s desire for a resilient, ball‑playing defender. Choosing between the two will involve weighing financial considerations against on‑field attributes. Stones would be a low‑cost, short‑term fix, but his injury history could limit his reliability.

Konsa, meanwhile, would require a significant outlay – Villa are said to be asking close to £60 million – yet he brings robustness, consistency and a proven record of staying fit. Arsenal’s defensive options are not limited to these two targets.

The club have already secured the permanent signing of Piero Hincapié after a successful loan spell from Bayer Leverkusen. In addition, they retain Gabriel, Riccardo Calafiori, Cristhian Mosquera, Jurrien Timber and Ben White as centre‑back alternatives. White has returned to training after a knee injury suffered in May, while Timber is optimistic about a swift return from a groin problem, stating he hopes to be back soon. The broader context of Arsenal’s transfer strategy includes a desire to blend experience with youth.

Stones, at 32, would provide veteran leadership, whereas Konsa, at 28, offers a blend of prime‑age athleticism and a few more years of top‑level service ahead. Both players can also fill in at right‑back if needed, adding tactical flexibility. Interestingly, statistical similarity tools do not rank Stones or Konsa among the top ten players most akin to Saliba across Europe’s major leagues.

According to Twenty3’s player‑similarity algorithm, the closest matches are Inter’s Manuel Akanji, Nice’s Kojo Peprah Oppong and Como’s Jacobo Ramon, all with similarity scores around 97 %. In the Premier League, only Chelsea’s Trevoh Chalobah and Manchester City’s Ruben Dias appear in the top ten, with scores of 94 %.

In summary, Arsenal face a pivotal decision as they seek to reinforce their back line after Saliba’s injury setback. John Stones presents a free‑transfer, experienced option with a known relationship to Arteta, albeit with a checkered injury past. Ezri Konsa offers durability, strong one‑on‑one defending and versatility, but at a considerably higher price tag. The club’s final choice will likely hinge on how they balance immediate defensive cover, long‑term squad planning and the financial realities of the transfer market.
