The West Ham United fans in the Transfer Tavern have been delighted by the manner in which their club have approached the transfer market so far this summer, but their most impressive summer deal could be on the horizon. 

The Breakdown

With the signings of Issa Diop, Ryan Fredericks and Lukasz Fabianski already secured, it seems the Hammers are set to embark on something of a spending spree during the summer transfer window.

The signings of Fabianski and Diop in particular represent smart moves to address problem areas of a West Ham squad which was lacking a significant layer of depth last season, but the clubs core problem remains unsolved: the lack of steel and quality in central midfield.

Mark Noble has been a loyal stalwart of the club throughout his career and a consistent performer who is willing to throw everything on the line for the claret and blue shirt, however, Manuel Pellegrini's options are relatively sparse beyond West Ham's captain who cannot be relied upon to single-handedly carry the midfield any longer.

With that in mind, it is hardly surprising that the club are interested in signing one of the standout players of the World Cup, namely Aaron Mooy (valued at £9 million by Transfermarkt), according to the Yorkshire Post.

The Australia international played an instrumental role in Huddersfield's survival bid last season and took his positive form to Russia where he was typically diligent and creative in central midfield.

Naturally, the Terriers will be in a strong position to command a higher transfer fee for his services on the back of his impressive showing in the World Cup, but that should not deter West Ham from tabling a generous offer this summer.

Pellegrini's priority in the market should revolve around his hunt for a central midfield player who is proven in the Premier League, available for a fair price, a quality technical talent and a hard-working grafter.

Within the current market Mooy is a player who undoubtedly fits the aforementioned description, so Pellegrini must do everything in his power to pull off a masterstroke transfer and bring him to the London Stadium before the season gets underway in August.
