Borussia Dortmund's 10 best signings of the decade (2010-2019)

#4 llkay Gundogan (2011)

Ilkay Gundogan scored Dortmund's goal in the 2012-13 Champions League final

German midfielder Ilkay Gundogan joined Borussia Dortmund from 1. FC Nurnberg for a fee of €4m in the summer of 2011, and almost instantly made an impact. He made 36 appearances in all competitions during his first season at the club, scoring 3 goals and making 3 assists, including the winning goal in the semi-finals of the DFB-Pokal, setting Die Schwarzgelben up for their league and cup double.

2012-13 then saw him establish himself as not just one of the best midfielders in Germany, but one of the best in Europe too. He made 45 appearances in all competitions, including 12 in the Champions League, as Dortmund made it all the way to the final before falling to domestic rivals Bayern Munich in a match that saw Gundogan score his side’s only goal.

The German international remained at the Westfalenstadion for a further 3 seasons, largely playing as a deep-lying playmaker and making use of his excellent range of passing, before 2016 saw him move to Manchester City for a fee of £20m as Pep Guardiola’s first signing at the club – essentially an acknowledgement of his tremendous talents.
