Although it was far from a dream start to Manuel Pellegrini's tenure in East London last weekend, West Ham brought in nine new first-team players this summer and the mood around the London Stadium should be high.
While their 4-0 loss to last year's Champions League finalists Liverpool may have highlighted that the former Manchester City boss still needs time to implement his trusty 4-2-3-1 formation, Pellegrini has offered a new attacking style that The Hammers can get behind.
One man who could epitomise the Chilean's new free-flowing style of football is Ukranian international Andriy Yarmolenko.
Making the move from Borussia Dortmund last month for a fee of £17.5million, the 28-year-old has previously attracted interested from across Europe and could prove to be one of the bargains of the summer.
Here at RealSport, we have taken a look at why the Ukranian international could be the man to spearhead the Hammers' push for European football.
