West Ham have wrapped up the signing of Andriy Yarmolenko after announcing earlier that the 28-year-old had joined from Bundesliga giants Borussia Dortmund on a four-year deal.

As well as Yarmolenko, the Hammers have added Issa Diop, Ryan Fredericks, Lukasz Fabianski and Jack Wilshere to the squad, but it is the Ukrainian winger who is the most exciting of the lot.

The Breakdown

According to Sky Sports, West Ham paid Dortmund a fee in the region of £17.5m for Yarmolenko, and in this inflated transfer market the deal for the Ukraine international can only be described as a bargain.

Albeit it did not quite work out for him in Germany, there is no denying the ability Yarmolenko has.

£20.7m-rated (via Transfermarkt) Yarmolenko arguably possesses one of the most underrated left foots in football, and is always a threat when cutting in from the right-hand side where he can then go on to either create a chance for a team-mate or bend one into the top corner.

At former club Dynamo Kyiv, Yarmolenko always impressed in the Champions League, and even last season at Dortmund, he put in a commendable performance against his new team's rivals Tottenham, scoring a beautiful curler away at Wembley.

Alongside Marko Arnautovic, Manuel Lanzini once he is fit again and the other of West Ham's rumoured transfer targets such as Bruno Fernandes and Felipe Anderson, Yarmolenko could help form part of an attack that the West Ham faithful have dreamt about for years.

Under a manager like Manuel Pellegrini as well, there is the expectation that Yarmolenko will be in an environment where he can truly express himself and ultimately be the part of something special at the London Stadium.
