Known for his detailed approach to coaching and a varied career spanning multiple countries, his 2025 year has been especially eventful, marked by difficult challenges, valuable lessons, and new opportunities.

Early Beginnings and Coaching Philosophy

Rubén Sellés’ journey began in the football-rich environment of Valencia, where he developed a deep passion for the game. His credentials include a master’s degree in Sports & Physiology from the University of Valencia and the prestigious UEFA Pro License, obtained by age 25—signaling his early commitment to combining scientific knowledge with practical coaching (). This blend of academic excellence and on-field experience shaped a philosophy centered on meticulous preparation, data-driven analysis, and player development.

Breaking Through in English Football

Sellés entered the English football scene notably in January 2022, bringing years of coaching experience from across Europe, including his time coaching at Valencia FC, FC Copenhagen, and Azerbaijani side Qarabag, where he was part of a historic Champions League group stage qualification (). His tenure in England has been a rollercoaster of transient successes and setbacks that reveal the harsh realities managers face in the Championship and Premier League.

Southampton Challenge and Leadership Style

His most high-profile English role came at Southampton FC, initially as first-team lead coach under Ralph Hasenhüttl. When Hasenhüttl departed, Sellés took over as interim manager in late 2022, managing a memorable penalty shoot-out win against Sheffield Wednesday, which endeared him to some fans (). His full-time appointment lasted until the end of the 2023 season. His period saw glimpses of tactical acumen and motivational skills, with notable wins against Chelsea at Stamford Bridge and home victories lifting the club briefly off relegation. However, relegation to the Championship was confirmed before season’s end (; ).

People widely recognise Sellés for his empathy and team management. He made efforts to strengthen team morale and player welfare by organising gestures such as sending gifts and vouchers to players’ families, aiming to foster a familial culture in a challenging environment (). These initiatives highlighted his understanding that football management goes beyond tactics—it is about human relationships and psychological support.

2025: A Tumultuous Year of Managerial Moves

Hull City and Sheffield United

2025 saw Sellés navigating rapid managerial changes with Hull City and Sheffield United. At Hull City, he managed to keep the club afloat in a competitive Championship league, avoiding relegation despite budget constraints and difficult circumstances (; ). His tenure, though marked by some skepticism from fans about promotion prospects, was valued for stabilising the team mid-table ().

On 18 June 2025, Sellés took charge of Sheffield United on a three-year contract, stepping into a club with lofty expectations after their previous playoff success. Unfortunately, the season unfolded disastrously for both him and the Blades. The team lost all their opening six league matches, including a heavy 5–0 defeat to Ipswich Town, leading to his dismissal on 14 September 2025 after just 6 games—the harsh reality of modern football management where results dictate tenure length (; ; ).

Supporters had mixed opinions: some argued for patience with Sellés given his prior achievements, while others were critical of the style of play and results (; ). The intensity of fan and media scrutiny in English football is unmatched and Sellés is learning firsthand the importance of managing not only players but also public and boardroom expectations.

Following his exit from Sheffield United, Sellés is poised to return to Spain as the head coach of Real Zaragoza (appointed October 2025), a historic club battling at the bottom of the Segunda División.
