German juggernaut Borussia Dortmund produced a scintillating display against Celtic at Signal Iduna Park in the Champions League on Tuesday.

Former Die Schwarzgelben academy graduate and current head trainer Nuri Şahin guided his side to an impressive 5-1 lead at half-time as the hosts stole the show.

While summer signing Serhou Guirassy bagged his fifth goal in his last four appearances for the Ruhr Valley outfit, it was German international Karim Adeyemi who pulled the strings for Dortmund.

A brilliant first-half hat-trick (from only three shots on target) all but guaranteed that Brendan Rodgers and company head back to Glasgow empty-handed.

Adeyemi is now the first German player to score a first-half hat-trick since Mario Gomez back in 2011 for Bayern Munich.

Unfortunately for the hosts, their star man was forced off after 50 minutes after an apparent hamstring injury. Following his European performance, Dortmund will hope it’s nothing too serious.
