Bilic has suggested that moving to the Olympic Stadium coupled with the attraction of the Premier League will see top footballers join the Hammers.
“The Premier League is attracting the best players in Europe and in the world, and then if you add to that the Stadium move and that we are the club from London that puts you in a position that you have no limitations,” the Croatian told West Ham’s official website.
“But you have to stay on the ground, and we have to plan slowly and we have to be realistic. There are no borders, to be fair, the sky is the limit, but step by step.”
West Ham signed a number of players in the summer transfer window, including attacking midfielder Dimitri Payet from Marseille and defender Angelo Ogbonna from Juventus.
The London outfit are having a great season at the moment and appear to be in the running for a top-four finish in the Premier League this season.
The Hammers are sixth in the league table at the moment with 21 points from 12 matches, just three points behind fourth-place Manchester United.
West Ham will take on London rivals Tottenham Hotspur away from home at White Hart Lane in the Premier League after the two-week international break.
