West Ham's co owner David Gold
Bilic has sent back loan players Victor Moses, Emmanuel Emenike and Alex Song to their respective clubs and is in need of midfield reinforcements at the end of last season.
West Ham have already been working hard to replace them after completing the signings of Norweigan midfielder Havard Nordveit and Algerian attacker Sofiane Feghouli on free transfers.
Hammers linked with top targets
The East Londoners are being linked with moves for a number of top strikers from across Europe including the likes of Lyon's Alexandre Lacazette, AC Milan's Carlos Bacca and Liverpool's Christian Benteke, as reported by Sky Sports.
Reports on the likes of Sky Sports have also speculated West Ham could sign Bestiktas star Gokhan Tore as the rumour mill goes into overdrive.

'Our fantastic recruiting team have worked tirelessly'
And now Gold, who tends to take more of a back seat in the everyday pursuit of targets, has sung the praises of West Ham's transfer committee in an interview with the club's official website.
"I want to pay tribute to our fantastic recruiting team who have worked tirelessly behind the scenes to make sure this deal got completed," Gold told whufc.com.
"David Sullivan, Slaven Bilic and Tony Henry make sure no stone is unturned as we look to bring the best players to West Ham United and have ensured we have brought another quality international into the squad. We have certainly got a good team of people on the case.
"The importance of making sure we make the right decisions when it comes to new players is such a key factor and we have a track record of bringing in the right players."

Change of tide with transfer policy
The Hammers have a fantastic record in the transfer market in recent seasons since a very deliberate change in club policy.
Gone are the days of West Ham signing players in the latter stages of their career or offering former stars one last big payday.
Nowadays the Hammers look to sign young, hungry and talented players who have good injury records and are predominantly aged under 27.
The signings of Dimitri Payet, Manuel Lanzini, Michail Antonio, Angelo Ogbonna, Cheikhou Kouyate and Aaron Cresswell in recent seasons are examples of the club's new recruitment policy at its best.
Meanwhile a host of outstanding younger players with potential to be future stars such as Martin Samuelsen, Antonio Martinez and Domingos Quina have been added to the ranks too.
