Top ten summer transfers
FIFA World Cup winner
Mario Götze was all smiles on his return to first club Borussia Dortmund following his three-year hiatus at FC Bayern München.
Former Dortmund captain
Mats Hummels moved in the opposite direction, and put in an imperious display as Bayern bettered BVB 2-0 in the Supercup at the SIGNAL IDUNA PARK.
Renato Sanches joined Hummels at the Allianz Arena from SL Benfica, having become the youngest UEFA EURO winner in history, helping Portugal to victory in France aged 18 years, ten months and 23 days.
Andre Schürrle joined Dortmund from VfL Wolfsburg the day after the Götze deal, to be reunited with his former 1. FSV Mainz 05 coach Thomas Tuchel.
Revierderby rivals FC Schalke 04 also bolstered their attack, with the acquisition of 19-year-old Switzerland star Breel Embolo from FC Basel 1893, who scored on his competitive debut against FC 08 Villingen in the DFB Cup.
After 12 goals and five assists for Stade Rennais FC in France's Ligue 1 last term, Dortmund's own 19-year-old
Ousmane Dembele (l.) has already looked like a menacing prospect in pre-season.
The Bundesliga's newest side RB Leipzig sealed one of the transfers of the summer when they picked up
Naby Keita (r.), with the Guinean midfielder having won back-to-back doubles with FC Salzburg.
Hummels' replacement at the heart of the
Schwarzgelben defence, Marc Bartra (l.) has brought the passing skills honed at FC Barcelona with him if his Supercup performance is anything to go by.
Passing the many new faces at BVB,
Jakub 'Kuba' Blaszczykowski brought nine years of service at the SIGNAL IDUNA PARK to a close by joining VfL Wolfsburg - but not before helping Poland to the quarter-finals of EURO 2016.
Wolfsburg continued to make waves with the signing of Kuba's former ACF Fiorentina teammate
Mario Gomez (c.). The Germany striker - a two-time Bundesliga winner - returns to the Bundesliga after three years away.
