Bayern made Hernandez the Bundesliga's record signing by splashing out €80 million ($89.7 million) for the versatile center-back, who will also provide cover for David Alaba. A powerful defender with plenty of room to grow, the 23-year-old is one of two members from France's World Cup winning side in 2018 set to join the club this summer…

…the other is fellow 23-year-old Pavard, who already has over 60 Bundesliga appearances to his name. After the triumph in Russia, it was clear the Frenchman was destined for bigger things and, while other sides were interested, Pavard claimed "Bayern were the only ones for me". €35 million ($39.2 million) looks to be an absolute bargain.

With Julian Nagelsmann Leipzig-bound, Hoffenheim are also set to lose a key figurehead on the pitch. Demirbay has come on leaps and bounds since moving to Sinsheim in 2016, having a hand in 38 goals (12 goals & 26 assists) in 87 appearances in all competitions, and wants to take the next step in Leverkusen with a view to adding to his 2 caps for the German national team.

A player that had caught the interest of Barcelona and Borussia Dortmund among others, 18-year-old Candido (right) has been touted as one of the hottest defensive talents in Brazil. A left-back trade with 8 appearances for Brazil's Under-20s to his name, Leipzig kept tabs on Candido for "half a year" before making the move to bring him to Saxony.

Wolf (center) boasts a wealth of experience and title-winning exploits that would be the envy of most players his age. A three time Austrian champion and a UEFA Youth League winner, the 20-year-old felt it was "time to take the next step". Since 2012, Wolf is the 18th player to move from Salzburg to sister club Leipzig, who wrapped up the transfer back in December.

After being relegated with Stuttgart in 2016 and Hamburg in 2018, few would have expected Kostic to be a contender for 'signing of the season' when he joined Frankfurt on a two-year loan deal. The Serb has been a revelation in Adi Hütter's system, playing in 45 of a possible 49 games in all competitions, making Eintracht's decision to trigger the buy-ou clause a no brainer.

With Paul Verhaegh leaving and reinforcements needed at right-back, Wolfsburg turned to four-time Switzerland international Mbabu (right). The 24-year-old, formerly on the books at Premier League outfit Newcastle, has featured in the Champions League and won back-to-back titles since making his loan move to Young Boys permanent in 2017.

With Oliver Glasner taking over as head coach in the summer, Wolfsburg have brought in one of the key members of his LASK side with Joao Victor making the move to Northern Germany. The 25-year-old Brazilian has had a hand in 31 goals (19 goals & 12 assists) in 33 games for the Austrian side in the current campaign.

Heavily linked with a move to Borussia Mönchengladbach, there was a surprise twist in the tale for Bebou when it was announced he had signed a contract until 2023 with Hoffenheim. The 25-year-old forward, who has 41 Bundesliga outings to his name, scored four goals and laid on three assists, but was limited to just 11 appearances due to torn thigh tendons.

With Germany international Nico Schulz reportedly set to leave the club, Hoffenheim have snapped up Augsburg's Stafylidis (right) to provide cover. The Greek left-back only made one appearance before Christmas, but has made nine starts in the second half of the season and is now "eagerly anticipating then chance to prove myself in this incredible environment" with 1899.

Hoffenheim triggered a release clause to make Adamyan (left) their first signing of the summer with sporting director Alexander Rosen referring to him as a "very exciting player". An international teammate of former Borussia Dortmund star Henrikh Mkhitaryan with Armenia, the 25-year-old has been in blistering form this season grabbing 15 goals and 11 assists in the 2. Bundesliga

Goller (center) first came to the attention of Bundesliga fans in December when he made his professional debut for Schalke, starting in their must-win UEFA Champions League group game against Lokomotiv Moskva. The winger hasn't featured for the Royal Blues since and, as a result, has sought out regular first-team football with a move to Bremen.

A product of Bremen's academy, Füllkrug (right) is set to return just under five years since he left to join Nuremberg. The striker's 14 goals helped Hannover survive the 2017/18 campaign, but cartilage damage in his knee restricted him to just 14 games and two goals this season. Nevertheless, Werder were willing to take the risk.

Ji (2nd from left) has been bouncing around the Bundesliga since joining Augsburg from Sunderland in 2013 and, after spells with Dortmund and Darmstadt, will make Mainz his fourth different station in Germany. The South Korean is still only 27 and, while he may not be the most prolific striker, he has a real penchant for scoring important goals. Just ask BVB.

The 28-year-old Belgian defender moves on a free to the capital, signing a deal until 2022. Business manager Michael Preetz said Boyata had been a target for some time. The Belgian joins having won eight trophies with Celtic, and a year after being part of Belgium's World Cup squad. Hertha also announced that captain Vedad Ibisevic had extended his contract for another year.
