The Most Expensive Transfers Ever: Updated With 2026 Deals
A definitive ranking of the 25 most expensive football transfers in history, updated with 2025-2026 transfer window activity, including Mbappé’s wage-driven move and Wirtz speculation.
The future of Kobbie Mainoo is one of the most anticipated transfer sagas of 2026. With Manchester City and Bayern Munich leading the chase, we analyze who holds the edge.
The Kobbie Mainoo transfer market has heated up dramatically as the 2025/2026 season enters its final stretch. At just 20 years old, Mainoo has emerged as a cornerstone of Manchester United’s midfield, delivering consistent performances across 38 Premier League appearances this season, scoring 6 goals and providing 8 assists. Despite his progression, United’s failure to qualify for the 2026/2027 UEFA Champions League has raised concerns about the club’s ability to retain top young talent.
Currently sitting in 7th place, United’s absence from Europe’s elite competition weakens their appeal compared to clubs already competing at that level. While Mainoo shares a strong relationship with manager Erik ten Hag and appreciates the club’s long-term vision, the lure of continental football is undeniable. His recent involvement with the England senior team, including a standout role during the 2024 Olympic campaign, has elevated his ambitions, pushing him to consider a move that accelerates his development.

Manchester City’s pursuit of Kobbie Mainoo is rooted in both short-term need and long-term planning. Having secured the 2025/2026 Premier League title by a narrow margin over Arsenal, City are preparing for life beyond Rodri, whose contract expires in 2027. With Mateo Kovačić aging and Phil Foden often deployed in advanced roles, Pep Guardiola sees Mainoo as the ideal candidate to inherit the defensive midfield mantle while contributing to buildup play.
Tactically, Mainoo’s composure on the ball, positional discipline, and ability to transition quickly align perfectly with City’s possession-based philosophy. His experience in high-pressure situations at United has demonstrated his mental resilience. Financially, City can offer a competitive salary package—reportedly up to £10 million per year—and the promise of immediate Champions League football. Staying in England also reduces relocation challenges, making the move more attractive.
Bayern Munich are mounting a serious challenge in the Kobbie Mainoo transfer race. After winning the Bundesliga and DFB-Pokal double in 2025/2026, the Bavarians are restructuring their midfield, particularly with Joshua Kimmich transitioning into a hybrid leadership role. Mainoo’s athleticism, technical precision, and pressing ability match Bayern’s recruitment profile under sporting director Christoph Freund.
Bayern can guarantee Champions League football and offer a starting role in a more central position than he might initially receive at City. The club is reportedly willing to pay a transfer fee of around £60 million, with a salary of approximately £7 million annually. However, cultural adaptation and the intensity of media scrutiny in Germany could be deterrents. While Bayern has successfully integrated young international talents before, the lack of an established English-speaking core may influence Mainoo’s comfort level.
Despite strong interest from both clubs, experts believe Kobbie Mainoo is more likely to join Manchester City. The combination of staying in the Premier League, working under Pep Guardiola, and immediate access to elite European competition gives City a decisive edge. Additionally, his existing rapport with Phil Foden and familiarity with the English football environment would ease his transition.
Bayern’s project is compelling, but City’s superior squad depth, global visibility, and proven track record in developing young midfielders tip the scales. A move to City would also position Mainoo as a key piece in a team still competing for multiple trophies annually. Our verdict: Mainoo will sign for Manchester City in summer 2026.
