West Ham United have had a quiet transfer window so far much to the frustration of their loyal fans.
Only Pablo Zabaleta has arrived in East London so far this summer on a free transfer from Manchester City.
Slaven Bilic has been linked with a plethora of players but supporters are beginning to lose patience with the club over a lack of signings.

But speculation has intensified this week and it seems the club are about to get serious on the transfer front.
The Hammers had a £15m bid for Arnautovic turned down this week and the Austrian international has since handed in a transfer request.
Meanwhile, West Ham are believed to have activated Hernandez's £13.5m release clause at Bayer Leverkusen but are in negotiations over his wage demands.
Hart has been linked with West Ham all summer and the Evening Standard reports Bilic wants to make the England international a "statement signing".

The media talk has got Hammers fans excited again at the prospect of a new-look forward line of Arnautovic, Hernandez and Michail Antonio supported by Manuel Lanzini.
That could see West Ham realistically compete for a place in the Premier League's top six after a disappointing campaign last term.
