Age: 21 Value: £2.8 million Nationality: German Position: Left Sided Midfielder After struggling to settle at Dortmund, Bittencourt became a first-team regular at Hannover where he scored four goals in 24 appearances for the club. Throughout his time at the club, Jurgen Klopp admitted that he was keeping an eye on the midfielder (and that he rated the player highly) but he decided not to activate the buy-back clause and the German U21 international moved to FC Koln this summer. Since then, Bittencourt has enjoyed the 2015-16 season and has grabbed two assists in eight games and aged only 21, has become one of the key figureheads in the side. The German isn't an orthodox winger and is widely praised for his industrious nature and tackling skills, (a bit like Dirk Kuyt, dare I say?).
