Porto's €65m clause tests United and Arsenal's patience

Manchester United and Arsenal are closely monitoring Porto right‑back Alberto Costa, the 22‑year‑old who arrived from Juventus in July 2025. In his debut season in Portugal he logged 47 appearances and supplied eight assists, while his contract carries a €65 million release clause. Both clubs see him as a potential future asset.

Contractual terms lock Porto in

Porto secured Costa from Juventus for €15 million, with up to €1 million in performance bonuses. The Portuguese side tied him to a contract running until June 2030, embedding the €65 million release clause. Juventus also retained a ten‑percent share of any future transfer profit.

Beyond United and Arsenal, Manchester City and Paris Saint‑Germain are reported to be tracking the defender. No formal bids have materialised, with interested parties still in the scouting and analysis phase. Porto’s strong negotiating position stems from the lack of urgency to sell.

Costa started five of Porto’s first six fixtures across the league and the Champions League. He completed the full ninety minutes against Manchester City, showcasing his stamina and defensive acumen. His attacking contributions, highlighted by eight assists, have drawn attention from clubs seeking modern full‑backs.

Club perspectives on Costa

Man United view Costa as a genuine competitor for the right‑back slot, aligning with their strategy of nurturing younger talent. The club believes his pace and recovery ability suit a high‑line defensive approach. United’s scouting report notes his versatility could see him develop into a long‑term starter.

Arsenal manager Mikel Arteta values defenders capable of operating in multiple phases, and Costa’s ability to push forward or sit deeper offers tactical flexibility. However, the potential outlay of €60‑65 million for a 22‑year‑old with limited top‑level experience raises financial concerns. Arteta’s assessment suggests the price tag may be a decisive factor in any eventual move.

Porto’s €65 million release clause makes any immediate purchase a major commitment for the English clubs. The Portuguese side’s leverage is reinforced by the clause and the fact that they do not need to sell. Should Costa continue to develop, the clause could appear less daunting in future negotiations.

Both United and Arsenal have opted to monitor the situation rather than rush into a deal. More coverage of the saga can be followed on CaughtOffside, which tracks the latest developments. For now, Porto retains almost all control over Costa’s future.
