Borussia Dortmund have been the most active team in Germany, with their Abdou Diallo acquisition as the most expensive transfer so far this summer.
Abdou Diallo (22) – Mainz to Borussia Dortmund (€28 million)
Diallo is a left-footed central defender who is technically strong and likes to build from the back while keeping the ball on the ground. He captains France’s U21 side and is a graduate of the Monaco academy. Between him, Dan-Axel Zagadou and Manuel Akanji, Borussia Dortmund now has three extremely gifted center backs who promise a bright future for the club.
Alassane Plea (25) – Nice to Borussia Monchengladbach (€22 million)
Plea is one of the most underrated forwards in European football. He was chased by more reputable clubs such as Tottenham and surprised everyone by joining Borussia Monchengladbach. He obviously felt he’ll get plenty of playing time here, in which case it would be another smart move by a very savvy player.
Thomas Delaney (26) – Werder Bremen to Borussia Dortmund (€20 million)
Delaney shined for Denmark during the 2018 World Cup and was especially effective in disrupting opposition play. He’ll give Dortmund some much needed strength in midfield.
Axel Witsel (29) – Tianjin Quanjian to Borussia Dortmund (€20 million)
The Westphalia outfit doubled down on defensive midfielders by bringing the vastly experienced Witsel back to the European continent.
Paulinho (18) – Vasco de Gama to Bayer Leverkusen (€18,5 million)
Paulinho is the latest Brazilian to be scooped up by Leverkusen’s scouting department. The bulky right winger shows excellent change of pace and will probably take over Leon Bailey’s spot in the starting lineup once he matures and Bailey departs.
Nordi Mukiele (20) – Montpellier to RB Leipzig (€16 million)
Having been chased by Manchester City and dubbed the next Lilian Thuram, Mukiele becomes the latest teenager to join RB Leipzig’s enthusiastic project. The right back immediately becomes a threat to take over Lukas Klostermann’s spot in the starting lineup.
Matheus Cunha (19) – Sion to RB Leipzig (€15 million)

Daniel Ginczek (27) – Stuttgart to Wolfsburg (€14 million)
Some might say Wolfsburg overpaid for Ginczek, but the club needed a striker and signed one they obviously thought fits their needs best. He scored the only goal in Wolfsburg’s German Cup first round victory over Elversberg, so he’s off to a good start.
Davy Klaasen (25) – Everton to Werder Bremen (€13,5 million)
Klaasen is an Ajax academy graduate, so even though his spell in England wasn’t fruitful, at 25, he’s still young enough to turn his career around.
Mitchell Weiser (24) – Hertha Berlin to Bayer Leverkusen (€12 million)
Selling talented young players to rivals is never a good idea, but Hertha was left with no option when Weiser decided to leave. In him, Bayer Leverkusen gets one of the most underrated right backs in German football.
With ten days to go before the transfer window closes in Germany, this list might still go through some changes, especially since Niko Kovac is yet to make a significant purchase at Bayern.
