Borussia Dortmund winger Andriy Yarmolenko decided to call it quits after just one season at the Westfalenstadion earlier this summer in favour of a move to the Premier League, with the Black and Yellows forced to take a €5m hit on their big money signing from last year.
The 28-year-old was Dortmund's biggest investment throughout both the summer and winter transfer windows last season. However, the Ukraine international, who for years was linked with a move to the club, arguably had the smallest impact out of any of their signings throughout 2017/18.
Yarmolenko scored six goals and claimed the same number of assists during his maiden year in Germany, an unimpressive, albeit far from catastrophic, tally for one of European football's major leagues.
