#5 Andriy Yarmolenko (Borussia Dortmund to West Ham)
Five years ago, £17.5 million for Yarmolenko would have been a bit of a bargain. However, the Ukrainian winger is a much different player to what he was a few years ago, and he hasn’t quite fulfilled his potential. Having spent much of his career in Ukraine with Dynamo Kiev, he moved to Borussia Dortmund last season, but having made just 18 Bundesliga appearances last season, he has moved on to West Ham.
He still has the quality to be a good player, but West Ham have taken on a man who has come off perhaps his worst season in professional football, down to injuries and poor form. There have also been questions asked about his temperament in the past, and that is an area West Ham have suffered in the past. Some may see it as cheap, but a question worth asking in that regard, is why are Dortmund so willing to sell?
