As the European Transfer Window approaches its halfway mark for the Summer, I decided to take a look at a few of the biggest done deals in the Bundesliga thus far.
Maximilian Kruse to Wolfsburg:
With the deal agreed long before the transfer period had even entered full swing, Wolfsburg's addition of Max Kruse bodes even greater title challenging ambitions. The Wolves finished runners-up behind Bayern Munich in the league standings last season and will no doubt look to improve.
Kruse arrives at the Volkswagen Arena after Wolfsburg successfully met the undisclosed release-clause set within his contract. The German international scored 23 goals during his two seasons with Borussia Monchengladbach and proved to be a significant figure in Lucien Favre's set-up as they finished third and secured UEFA Champions League qualification.
Nevertheless, the 27 year-old will now link up with his new teammates ahead of the new campaign as they try to improve on last season's domestic feats. Kruse headlines as Wolfsburg's only high-profile signing within the window thus far - aside from the arrival of 20 year-old Swiss midfielder, Francisco Rodriguez from FC Zurich.
Gonzalo Castro to Borussia Dortmund:
Castro joins Dortmund as new manager Thomas Tuchel's biggest signing since taking charge of the side after Jurgen Klopp's departure. After developing within the Bayer Leverkusen youth ranks as a teenager, the German international went on to play 11 seasons with the club and became arguably one of their most important players.
Despite Leverkusen finishing fourth and qualifying for Champions League football this upcoming season, the 28 year-old has joined the BVB on a four-year deal reportedly worth around the figure of €11m (16.6 AUD). The deal comes as Dortmund look to bounce back from a hugely disappointing 2014/15 season which saw them finish in seventh place.
Castro adds creativity, stamina, an eye for goal and his mould contains similar characteristics to that of Ilkay Gundogan. As a result, he will be eager to prove his worth at the Signal Iduna Park alongside fellow Summer arrivals Julian Weigl and Roman Burki.
Arturo Vidal to Bayern Munich:
Without doubt, the biggest move of the Summer thus far has seen Arturo Vidal join Bayern Munich on a four-year deal worth €37m (56m AUD) alongside a potential increase of €2.1m. After four years and four Serie A titles in Turin, it appears time for a fresher challenge.
The Chilean joins the Bavarian club looking for further success both domestically and continentally. His workhorse-like mentality and engine within midfield in transition is a quality that Bayern will welcome with open arms after recently selling club legend, Bastian Schweinsteiger, to Manchester United.
The Reds strolled their way to their third successive Bundesliga title last season but ended their campaign in disappointment once again after they failed to reach UEFA Champions League success. As a result, it comes without question that this will be the key objective for Guardiola and co. come the new season. Vidal's arrival at Allianz Arena this Summer is welcomed alongside new recruits Sven Ulreich and Douglas Costa.
Big money moves have been few and far between thus far for the Bundesliga, but perhaps a couple more deals remain in the offing between now and the window’s closing.
