Summer 2025 Transfer Round-Up: Major Deals Confirmed Ahead of Window Opening

As the 2025 summer transfer window approaches its official opening on July 1, several high-profile deals have already been finalized, setting the stage for an exciting summer of football business. Clubs across Europe have wasted no time, securing impactful signings to reinforce their squads well before pre-season preparations begin.

Premier League Activity

Arsenal's Midfield Reinforcement: Martin Zubimendi

Arsenal have confirmed the £51 million signing of Spanish midfielder Martin Zubimendi from Real Sociedad. The 26-year-old, who played a key role in Spain’s Euro 2024 success, arrives as a tactically astute deep-lying playmaker. Known for his exceptional positional sense and passing range, Zubimendi is expected to anchor Mikel Arteta’s midfield as the Gunners prepare for another Champions League push.

Chelsea’s Strategic Moves: Liam Delap & Rising Portuguese Stars

Chelsea have moved early to reinforce their attack, triggering the £30 million release clause of Ipswich Town striker Liam Delap. The 22-year-old, a Manchester City academy graduate, impressed in the Premier League last season with his physicality, intelligent movement, and goal-scoring instincts. Delap’s arrival provides new manager Enzo Maresca with a familiar and potent option up front.

Furthermore, Chelsea have secured a £62.5 million double deal for Sporting CP starlets Dário Essugo and Geovany Quenda. Essugo, an 18-year-old defensive midfielder, has already made over 30 senior appearances and is touted as a future Portugal international. Quenda, a dynamic winger with flair and speed, has shone at youth level for both club and country. These signings underline Chelsea’s long-term investment in emerging talent.

Liverpool's High-Stakes Reinforcement: Florian Wirtz & Jeremie Frimpong

Liverpool are poised to break the British transfer record with a £126 million deal for Bayer Leverkusen playmaker Florian Wirtz. At just 22, Wirtz has already established himself as one of Europe’s most creative midfielders, blending dribbling skill, vision, and clinical finishing. His arrival is set to mark a new attacking era under Arne Slot.

The Reds are also finalizing a £29.5 million move for Jeremie Frimpong, Wirtz’s Leverkusen teammate. The Dutch right-back, known for his blistering pace and attacking instincts, will add vital depth and competition, especially with Trent Alexander-Arnold reportedly on his way to Real Madrid.

West Ham's Youth Investment: Daniel Cummings

West Ham United have completed the signing of 19-year-old striker Daniel Cummings from Celtic for a compensation fee of £300,000. The prolific youth scorer — with 30 goals last season — is seen as a long-term attacking option for the Hammers, and will join formally on July 1.

Continental Transfers

Bayern Munich’s Defensive Boost: Jonathan Tah

Bundesliga champions Bayern Munich have snapped up Jonathan Tah on a free transfer following the expiration of his Bayer Leverkusen contract. The 29-year-old centre-back brings over a decade of top-flight experience and was instrumental in Leverkusen’s historic 2023–24 title-winning season. His arrival provides leadership and physical presence to Bayern’s defensive core, filling a key gap as the club rebuilds its backline.

Brighton's Global Scouting Pays Off: Yoon Do-young & Tom Watson

Brighton & Hove Albion continue their tradition of smart scouting by securing two exciting young wingers.

Yoon Do-young, signed for £2 million from South Korean side Daejeon Hana Citizen, is an 18-year-old sensation with explosive pace and technical flair. He debuted in May 2024 and quickly caught attention with his fearless dribbling and vision.

Tom Watson joins from Sunderland in a £10 million move, having impressed in the Championship with his mature wing play and versatility across the front line. Both players are expected to either compete for minutes or be loaned to gain experience — reflecting Brighton’s long-term squad building strategy.

Looking Ahead

The early activity in the transfer market signals a thrilling summer ahead. With strategic investments, marquee arrivals, and youth-focused acquisitions, clubs are positioning themselves for success both immediately and in the future. As the window officially opens, fans can expect even more movement and surprises as teams finalize their squads.
