Table of contents
1. Florian Wirtz to Liverpool
Florian Wirtz, just 21 years old, has starred in the most expensive transfer of the window so far: €125 million paid by Liverpool to Bayer Leverkusen. A creative attacking midfielder with precision and vision, Wirtz arrives to lead the Reds’ new project under Arne Slot.
His ability to break lines, his maturity, and football IQ make him a cornerstone of Liverpool’s future.
2. Trent Alexander-Arnold to Real Madrid
Former Liverpool captain Trent Alexander-Arnold has joined Real Madrid for a fee close to €75 million. At 26, he is one of the world’s most impactful full-backs, and his arrival addresses the club’s need to strengthen the right side after Carvajal’s departure.
His passing range, interior vision, and leadership add a new layer to Madrid’s attacking build-up.
3. Dean Huijsen to Real Madrid
Another key move is the permanent signing of Dean Huijsen, the Dutch-Spanish central defender, into Real Madrid’s first team from Juventus. The club paid around €25 million plus bonuses, betting on him as a pillar for the future.
Technical, composed, and with excellent ball distribution, Huijsen fits the mold of the modern defender Madrid wants to consolidate.
4. Matheus Cunha to Manchester United
Manchester United has strengthened its forward line with the signing of Matheus Cunha, the Brazilian striker from Wolverhampton, for £62.5 million. With mobility, goals, and pressing ability, Cunha brings fresh solutions to Rubén Amorim’s attacking plans.
His Premier League experience and positional versatility make him a dependable signing.
5. João Pedro to Chelsea
Brazilian attacker João Pedro, 22, becomes a Chelsea player after a strong season with Brighton. The deal closed at £60 million, and he is expected to add flair and scoring instinct to the Blues’ young squad.
Fast, skillful, and strong, Pedro fits perfectly into Chelsea’s recruitment strategy focused on high-potential youth.
6. Tijjani Reijnders to Manchester City
Dutch midfielder Tijjani Reijnders, signed for £46.3 million from AC Milan, is Manchester City’s latest midfield addition. His tactical intelligence and physical presence make him ideal for Guardiola’s system, as City refreshes its core.
Accurate passing, constant movement, and game reading define his playing style.
7. Jeremie Frimpong to Liverpool
Liverpool’s third major signing is Dutch wing-back Jeremie Frimpong, acquired from Bayer Leverkusen for £34 million. With blistering pace and offensive drive, he resembles players like Alphonso Davies on the flank.
Frimpong brings speed, energy, and width to the team’s dynamic system.
8. Hugo Ekitike to Liverpool
Finally, Liverpool has also secured Hugo Ekitike, a 23-year-old French striker, for €95 million from Eintracht Frankfurt. A powerful, direct forward with aerial ability and poise, he is expected to become the Reds’ new No. 9.
He’s seen as a long-term replacement for Darwin Núñez.
Formation and future vision of the signings
What most of these signings share is a common thread: they are young players with comprehensive training backgrounds, both physically and tactically. This mirrors the educational-sporting model developed by SIA Academy, where footballers not only learn how to play but how to understand the game, take care of themselves, and professionalize their careers from the ages of 12–18.
Players like Huijsen or Ekitike could have easily followed a path like the one offered by SIA Academy: individualized coaching, academic structure, sports science, and a competitive mindset. The 2025 market proves that elite clubs now value not just talent, but structured development.
Youth, ambition, and millions
The 2025 summer market shows a clear strategy from top clubs: invest in young players who offer immediate impact and long-term growth. Liverpool, with four major additions, and Real Madrid, with a bold defensive rebuild, have led the way.
Manchester United and Chelsea follow closely, targeting dynamic attackers, while Manchester City adds smartly to maintain continuity.
The role of academies like SIA Academy is more relevant than ever, as they prepare the next generation of players to meet these challenges from the ground up. In an era where training and performance go hand in hand, these signings are just the tip of the iceberg in a deeper transformation across European football.
