Bayer Leverkusen's Summer Overhaul Leads Europe's Busiest Transfer Window

Bundesliga

Bayer Leverkusen are the undisputed centre of this summer’s transfer activity, and the scale of their rebuild is striking. On the outgoing side, three high-profile departures stand out: left-back Álex Grimaldo has joined Atlético Madrid, defender P. Hincapié has moved to Arsenal, and midfielder M. Kovář has completed a permanent switch to PSV Eindhoven — all confirmed on 30 June. The loss of Grimaldo and Hincapié in particular represents a significant defensive shake-up at the BayArena, with two regular starters departing in the same window.

To replenish the squad, Leverkusen have moved decisively in the market. Kerim-Sam Alajbegović has arrived from Red Bull Salzburg, A. Damjanović from FK Crvena Zvezda, K. Eichhorn from Hertha BSC, and Afonso Moreira from Lyon — all on 30 June. Luca Erlein has also joined from 1899 Hoffenheim, confirmed in late July. V. Boniface has returned from his loan at Werder Bremen and is back in Leverkusen’s plans, while M. Kovář himself returned from a loan at PSV before his permanent exit was formalised — a sequence that reflects the administrative tidying-up common at the end of a contract cycle. The pattern is clear: Leverkusen are shedding experience and wages while simultaneously bringing in younger, hungry talent from across Europe.

Among the exits, Ken Izekor has joined Alemannia Aachen on a permanent basis, I. Traore has gone to AS Trenčín on loan, Francis-Ikechukwu Onyeka has joined SV Elversberg on loan, F. Pohl has left as a free agent to join Utrecht, and E. C. Owen has also moved to Utrecht on a permanent deal. A. Sarco, meanwhile, has headed to Sporting Gijón. The volume of departures — spread across Germany, the Netherlands, Slovakia, and Spain — suggests Leverkusen are conducting a thorough squad audit rather than merely trimming at the edges.

La Liga

Atlético Madrid have made one confirmed arrival this window: Álex Grimaldo, the Spanish left-back who departs Leverkusen after an influential spell in Germany. It is a statement signing for Diego Simeone’s side, adding proven top-level experience to their defensive options.

Premier League

Arsenal have secured the services of defender P. Hincapié from Bayer Leverkusen, the Ecuadorian’s move to north London confirmed on 30 June. It is the only confirmed Premier League move in this dataset, but it is a notable one — Hincapié arrives with Bundesliga and international pedigree.

Eredivisie

PSV Eindhoven have confirmed the permanent signing of M. Kovář from Leverkusen, while Utrecht have picked up both F. Pohl (free agent) and E. C. Owen (transfer) from the same club. Utrecht’s double-dip into Leverkusen’s outgoings suggests an established working relationship between the two clubs this summer.

Segunda División

Sporting Gijón have brought in A. Sarco from Bayer Leverkusen, a further sign of the German club’s willingness to move players on across multiple leagues and levels this summer.
