The most underrated signings of the 2025-26 season across European football

Published 2026-03-17

Remember that €8 million Southampton coughed up for Virgil van Dijk? Or the measly €10 million Leicester sent Sporting’s way for Youri Tielemans? Every season, while the headlines scream about nine-figure transfers and Galactico arrivals, a few quiet deals slip under the radar, only to blossom into absolute steals. The 2025-26 season is no different. Forget the Mbappé-to-Real sagas for a moment; these are the unsung heroes, the undervalued gems who will outperform their price tags tenfold.

The Serie A Scavenger: Gianluca Mancini to Roma (Free Transfer)

Okay, so it’s a return, but hear me out. Mancini left Roma in a messy deal for a supposed upgrade to the Premier League that never materialized. He spent one dismal season at Nottingham Forest, largely injured and mismanaged. Roma, under their new data-driven Sporting Director, swooped back in when Forest released him. It’s a free transfer for a player who, in his last full season in Serie A, averaged 1.8 interceptions and 3.5 clearances per 90 minutes. He’s a leader, a proven Serie A commodity, and precisely the kind of no-nonsense defender Roma’s often-flaky backline needs. This isn't just depth; it's a statement.

Bundesliga Bargain: Noah Mbamba to Bayer Leverkusen (€7 million from Club Brugge)

Leverkusen’s recruitment has been nothing short of genius for years, and they’ve done it again. While everyone was fixated on Xabi Alonso’s future, they quietly secured Mbamba, a defensive midfielder with the physique of a seasoned pro and the passing range of a playmaker. He barely featured for Club Brugge’s senior team, making only 10 appearances, but scouts have been raving about him for years. This kid is a project, yes, but at €7 million, he’s a low-risk, sky-high-reward signing. Expect him to be rotating with Palacios by the winter break and attracting €50 million bids by 2027.

La Liga’s Loan Masterstroke: Nico Williams to Real Betis (Loan from Athletic Bilbao with €25 million option)

Athletic Bilbao are notoriously tough negotiators, but Betis pulled off a coup here. Nico Williams, often overshadowed by his brother Iñaki, is a winger of immense talent, but his development has stalled slightly in the crowded Athletic attack. Last season, he contributed 5 goals and 7 assists in La Liga, often in a rotational role. A full season as the undisputed starter on the left wing at Betis, under Manuel Pellegrini’s expansive system, will unlock his true potential. The €25 million option feels like a steal for a Spanish international who could easily be worth double that if he hits his stride. This isn't just a good signing; it's a potential heist.

While the footballing world drools over the latest nine-figure transfer, these are the deals that will truly shape the season. They're not flashy, they're not headline-grabbing, but they are the bedrock of success. My bold prediction? By May, Nico Williams will be the most talked-about winger in La Liga outside of Madrid and Barcelona, forcing Athletic Bilbao to regret that €25 million option more than they regret any missed penalty.
