The 23-year-old has established himself as a key figure in Diego Simeone's defence since a slow start to life at the Metropolitano, racking up 39 competitive appearances with two goals and an assist, and has since forced his way into Spain's senior squad.
According to Fussball-News, scouts from all four English clubs have been tracking his progress, drawn to his physical and technical attributes as well as a versatility that allows him to play both centre-back and right-back.
Any move looks difficult to engineer. Pubill's contract runs until June 2030, and Atletico Madrid have already made clear they have no intention of facilitating a sale, protecting him with a release clause reported to be worth around €500 million.
Fussball-News suggests a fee closer to €60 million would be needed simply to convince Atlético's hierarchy to sit down and negotiate, though that figure falls well short of the release clause itself.
Pubill's rise has been a rapid one. He joined Atlético from Almería for around €16 million in the summer of 2025 after playing second-division football as recently as May of that year, and struggled initially to break into Simeone's side, not making his first start until late November in an unfamiliar central defensive role.
Since then he has become increasingly indispensable, helping Spain win the World Cup this summer and drawing interest from Arsenal in particular, who made concrete enquiries over a move last season before being rebuffed by an Atlético hierarchy unwilling to entertain offers.
Pubill's versatility has become his calling card. Comfortable operating either as a central defender or a right-back, he offers Premier League suitors a rare blend of physical presence and adaptability at a time when several English clubs are searching for cover across multiple defensive positions rather than committing to single-role specialists.
Arsenal are said to view him as an option to add depth following an injury to William Saliba, while Manchester United, Chelsea and Liverpool are each believed to be exploring reinforcements in a similar area of the pitch.
With Atlético showing no willingness to budge and a nine-figure release clause acting as a further deterrent, any of the four clubs would face a genuinely difficult negotiation if they wish to test his availability before values shift again in future windows.
