4. Henrikh Mkhitaryan
The Armenian already has Champions League credentials when arriving at the Westfalenstadion this summer, having impressed in the competition with Shakhtar Donetsk.
Mkhitaryan was bought in to replace the departing Mario Goetze and despite having such big boots to fill, has taken to life at Dortmund immediately.
The 24-year-old has five goals and four assists in all competitions this season and netted the first against Wenger’s men two weeks ago.
