Manuel Pellegrini has secured his second signing of the week, with Andriy Yarmolenko completing a reported £17.5m move to the London Stadium from Borussia Dortmund.

The Ukraine international has signed a four-year contract with the Hammers and becomes their fifth summer signing, following in the footsteps of former Arsenal midfielder Jack Wilshere, who penned a three-year deal with the club earlier this week.

Yarmolenko, who can play out wide or as a forward, arrives in East London after just one season with Dortmund in the Bundesliga where he scored six goals in 26 appearances in all competitions, but struggled to hold down a regular place in the starting line-up.

Prior to joining Dortmund last summer, the 28-year-old spent nine years with Dynamo Kiev, establishing himself as the club’s talisman having notched 137 times in 341 games in all competitions.

Yarmolenko also has an excellent goal scoring record at international level as well, with only Andriy Shevchenko scoring more times for Ukraine than the 28-year-old.

Speaking to West Ham’s website, Yarmolenko said: “Of course, I am very happy to sign for West Ham United.

"West Ham is a big club with good fans and I am happy to come to play in the Premier League. 

"The Premier League is the best league in the world and I know that an interesting project is being built here at West Ham. The team wants to achieve high things and I am excited for this challenge."

Mario Husillos, West Ham’s director of football, added: “We are very happy to welcome Andriy. When we had the opportunity to sign him, we did not hesitate, because he really is the kind of player that we were looking for.

“He is a left-footed player but can play on the right and is very quick, very good one-on-one against a defender. He gives the team a lot of attacking options and scores goals, is fast on the counter-attack and provides aerial threat with his height.

“He also has very good experience, of playing for big teams and fighting for titles. At Dortmund, he had some good matches but perhaps didn’t quite show his very best. However, I think Manuel Pellegrini is the perfect coach for Andriy and his style of play. 

“I believe he is joining us in the perfect moment. He is 28, the prime age for football, and we have great expectation about what he can achieve with West Ham United."
