West Ham United midfielder Cheikhou Kouyate has injured himself in training.
West Ham have been training in Austria, ahead of the new campaign, and have managed to largely avoid injury so far.
However, Kouyate has picked up a knee complaint in training.
And Bilic said: “The only one problem we’ve had is with Cheikhou, who injured his knee in a very strange and awkward way during training, but apart from that I’m happy with everything.
“The boys are training hard, they are pushing really hard, the facilities are really good and it is a great place to be.”
West Ham played a pre-season friendly against Sturm Graz yesterday, and it appears Bilic’s side still need to sharpen up before the new campaign.
The Hammers could only pick up a 0-0 draw in the contest, with their finishing poor throughout.
West Ham are known to be on the look out for new additions in the coming weeks, as Bilic looks to freshen his side up.
The Hammers were in disappointing form last campaign, and lacked the consistency to challenge for a European spot.
Bilic has so far only been able to bring in Argentine defender Pablo Zabaleta on a free transfer, after his contract at Manchester City expired.
