West Ham United boss Slaven Bilic has promised big things at the club as he looks to bring in more players before the start of the domestic season.

The Hammers have signed midfielders Dimitri Payet for £10.7million from Marseille and Pedro Obiang for £4.3million from Sampdoria as well as Irish goalkeeper Darren Randolph on a free transfer from Birmingham.

"Our plan is to bring in more players," he said. "We are trying to bring in players who we believe can lift us to another stage and make us better.

"We have already signed a few players and brought them into a good team. Sometimes they will click straight away and sometimes it will take a bit of time.

"We are aware of that and we are going to try and make that adjustment period as short as possible.

"We are expecting big things with West Ham. We are not big headed and will take it step by step but the early signs are very promising."
