The most impressive rookies in European football

The 2025/26 season is seeing numerous new signings who rapidly adapt and immediately become pillars, sometimes changing the landscape at leading European teams.

The 2025 transfer window was not only active in numbers but also delivered significant sporting impacts, as many new players instantly elevated their teams and shifted the competition in Europe’s top leagues.

Luis Diaz (From Liverpool to Bayern Munich)

After Leroy Sane left Allianz Arena, Bayern Munich had to find a top-class option for the left flank. Nico Williams was initially targeted, but his contract extension with Athletic Bilbao led the German club to turn to Luis Diaz. At 28, doubts were raised about his ability to fit into Vincent Kompany’s system, but the reality proved completely opposite.

Joining Bayern for £65.5 million, Diaz exploded onto the scene. In 30 appearances across all competitions, he contributed 32 goals and assists. His hat-trick and two penalties in the 5-1 win over Hoffenheim clearly demonstrated his quality. His speed, skill, and creativity have drawn comparisons to Franck Ribery. Meanwhile, Liverpool has struggled and is fighting hard in the Premier League’s top race, highlighting the huge gap Diaz’s departure left.

Gianluigi Donnarumma (From PSG to Man City)

Man City attracted attention by spending €35 million to sign Gianluigi Donnarumma as Ederson’s replacement. The Italian goalkeeper signed a 5-year contract and quickly became a reliable last line of defense in Pep Guardiola’s system.

Initially, there were doubts about his footwork and adaptation to a possession-based style, but Donnarumma responded with consistent performances and numerous top-class saves. His solidity has helped Man City maintain second place in the Premier League after 25 rounds, closely chasing Arsenal. At 26, Donnarumma is entering his prime and forming the foundation for the club’s long-term ambitions.

Bryan Mbeumo (From Brentford to MU)

MU spent £64 million to acquire Bryan Mbeumo, a transfer that sparked much debate. However, the Cameroonian forward quickly proved his worth with consistent output and dynamic play.

After scoring 20 goals and providing 8 assists for Brentford last season, Mbeumo has maintained his form at Old Trafford. He has played a key role in the unbeaten streak under interim coach Michael Carrick, especially dangerous on counterattacks. His versatility on both wings makes him a crucial tactical weapon. Many experts consider Mbeumo a strong candidate for MU’s most successful signing this season.

Luka Modric (From Real Madrid to AC Milan)

At 40 years old, Luka Modric still delivers impressive performances for AC Milan. Leaving Real Madrid after many years, he continues to demonstrate his value through endurance and game control.

Modric is among the players with the most minutes played in Serie A for Milan and ranks high in ball recoveries, interceptions, and accurate passing. His presence helps Milan compete fiercely in the Scudetto race. Meanwhile, Real Madrid faces physical and depth challenges, further highlighting Modric’s former influence.

Marcus Rashford (From MU to Barcelona)

After falling out of MU’s plans, Marcus Rashford was loaned to Barcelona and quickly revived under Hansi Flick’s leadership.

He has scored 4 goals and provided 8 assists in La Liga over 21 matches, contributing to 23 goals in all competitions. Rashford’s pace and finishing offer Barcelona a direct attacking option. The Catalan club is considering a permanent deal for around £26 million, proving this is one of the season’s most effective transfers.
