Arsenal tested the waters for Atlético's World Cup full-back

Player

Marc Pubill — right-back, Spanish international, reportedly part of Spain's 2026 World Cup squad per Foot Mercato.

Current club

Atlético de Madrid. Pubill had an excellent 2025-26 season under Diego Simeone, establishing himself as a genuine first-choice option at right-back. Atlético view him as a key part of their squad going forward.

Linked club

Arsenal. Mikel Arteta's side have been active in the full-back market and the reported interest in Pubill fits a pattern — a technically capable, high-energy defender who can function in a press-heavy system.

Source

Foot Mercato (France), reporting on 14 August 2026. No corroboration from a second outlet at time of writing.

Reliability

This is early-interest territory, and even that may be generous. Foot Mercato is a credible French outlet but this report stands alone — no Romano, no Athletic, no Sky Sports corroboration. The framing from Foot Mercato itself suggests Arsenal's approach was exploratory rather than a formal bid, and Atlético's position is that Pubill stays. Treat this as a probe that didn't go anywhere, for now. No second source has picked this up at time of publication.

The claim

Arsenal made contact — the nature of that contact isn't specified — to test Atlético's willingness to sell Pubill. Atlético, per the report, are not interested in doing business. Pubill is expected to remain in Madrid.

Does the logic hold?

Arsenal's right-back situation has been a recurring conversation at the Emirates. Pubill — a World Cup winner with proven top-flight experience in La Liga and the Champions League, per Foot Mercato — would represent a genuine upgrade in profile. He fits the athletic, technically sound mould Arteta tends to favour in his defensive line. The logic of the interest is sound, even if the execution appears to have stalled before it started.

Atlético, for their part, are not a club that sells key players cheaply or quickly. Simeone's sides are built on continuity and defensive solidity — losing a right-back who just won a World Cup, mid-window, would be a significant disruption. Diego Simeone did not use the word 'sell' once in his last press conference. We're guessing.

If a second outlet picks this up, revisit. Until then, file it under homework.
