Signed from Karlsruher SC in summer 2012, Calhanoglu enjoyed his breakthrough Bundesliga season at Hamburg in 2013/14. The Mannheim-born playmaker scored 11 goals, the highlight being a 50-yard free kick against Borussia Dortmund, and chipped in with four assists as HSV clung on to their top-flight status thanks to a play-off win over SpVgg Greuther Fürth.

His dead-ball prowess the envy of many, the Turkey international joined Leverkusen in July 2014 and has since chalked up 18 goals and 13 assists in 60 appearances in all competitions for the Rhineland club. Curiously, his postage-stamp set piece against FC Bayern München on 2 May 2015 was the first direct free-kick Manuel Neuer had ever conceded in the Bundesliga.

After a year in the Leverkusen youth team, burly striker Lasogga made just five appearances for the senior reserves before being deemed surplus to requirements in 2010. The former Germany Under-21 international enjoyed far greater success at his next station, Hertha Berlin, but after helping the capital outfit earn promotion to the Bundesliga in his first season at the club, injuries began to take their toll.

A fruitful loan spell at HSV followed, with a permanent deal the reward for his 13-goal Bundesliga haul in 2013/14. He managed to find the net just four times in 20 Bundesliga appearances the following season, but already has three goals to his name in 2015/16.

Adler was once a mainstay between the posts for Leverkusen after making his Bundesliga debut in a 1-0 win away to FC Schalke 04 in February 2007. The Leipzig native kept 55 clean sheets in 173 first-team appearances in all competitions for Die Werkself, only to lose his place in the starting XI due to a combination of injuries and the form of Bayer 04 newcomer Bernd Leno.

He missed just two outings in his debut season at new club Hamburg in 2012/13, but has made just 45 top-flight appearances since, including only three so far this term.

Two years ago, Tah became the youngest Bundesliga debutant ever to pull on a HSV shirt. The uncompromising centre-back appeared to be on the right track long before his move to Leverkusen, but after falling out of favour at Hamburg under Mirko Slomka in 2013/14, his search for first-team football took him out on loan to Bundesliga 2 outfit Fortuna Düsseldorf.

Although Düsseldorf finished the 2014/15 campaign 14 points adrift of the promotion places, Tah’s time in the shop window proved a roaring success, with Leverkusen snapping up the towering Germany U-19 captain on a five-year deal this past summer. He has has not missed a single minute of action at home or abroad all season.

Bruno Labbadia

After calling time on a playing career spanning over 20 years, Bruno Labbadia went straight into coaching in 2003. He took up his first post with hometown club SV Darmstadt 98, before taking charge of Fürth for the 2007/08 campaign. His stock rising, the former two-time Germany international striker joined Bundesliga stalwarts Leverkusen a year later, only to leave the club the following summer to link up with old flame Hamburg.

Labbadia was relieved of his duties after HSV finished seventh in 2009/10, but that was not the last the Hamburg faithful had seen of him. With the club’s unique ever-present Bundesliga status hanging by a thread, Labbadia - head coach at VfB Stuttgart between December 2010 and August 2013 - returned to the hot seat in April 2015 to steer the Dinos clear of the drop via the play-offs.
