West Ham United Joint-Chairman David Sullivan is expecting another busy summer of transfer activity and hopes to sign a number of new players over the next few months.



Mr Sullivan is working tirelessly behind the scenes alongside Slaven Bilic to bring the best possible players to Club and has already made multi-million pound offers for some of the best talent in Europe.



West Ham have already announced the arrival of Norway international Havard Nordtveit, who will join up with his new team-mates at the start of July.



With the Club qualifying for the Europa League next season, the Board are determined to help Bilic possess the strength in depth to cope with the prospect of additional fixtures, should the Hammers progress into the group stage.



West Ham enjoyed a memorable campaign in the final ever season at the Boleyn Ground and much of that was down to the new arrivals who arrived last summer, including Hammer of the Year Dimitri Payet, Angelo Ogbonna, Manuel Lanzini and Michail Antonio.



Mr Sullivan is hopeful the Club can find the same calibre of players and says they will continue to work hard to get the best possible deals for West Ham United.



"We have done well with our signings and we hope we can sign a few more this summer who will do equally as well or better," he added.



“We know that we need a top striker which is the hardest thing to sign. We need a 20-goal-a-season striker and that will cost us £25m or £30million. That is where the bulk of the money goes.



“We also need the occasional long shot which is the cheaper player that may come good. We want to sign more players.



“There might be a few fringe players who we will let go and use that to bring in two or three more players.



“We have already signed one player for next season and there will be other signings. I would think that four, five or six players will come in this summer depending on how many go and hopefully we do just as well or even better next season.”
