The Baggies, who face Man United on Saturday, have played eight matches since returning to the Premier League.
But despite coming close against Chelsea, Burnley and Brighton, they are yet to register a victory.
Bilic, though, doesn’t want that playing on the minds of his players.
“We can’t be obsessed with that in a negative way,” the boss said when asked about whether the lack of wins is impacting his side.
“It will come, if we tick all the boxes we need to tick, it will come. It’s about us.
“We were so close to winning one of the toughest games on paper so far – we were very close against Chelsea.
“We aren’t going to win as many games as we did last season. Nobody expects us to do that.
“But in every game there is an opportunity for us to win it. In every game there is an opportunity.
“And what we can’t do is be desperate in a negative way, in a way that makes us lose confidence and belief.
“We can’t be like ‘oh my god we are not winning’. If we don’t win let’s draw and perform and win next time. That is how you stay in this league.”
Bilic says maintaining belief is absolutely key to Albion’s hopes of staying in the Premier League.
“We have to believe, we have to get that first win as soon as possible and then the second and third one,” the 52-year-old continued.
“We cannot stop believing because in many of the games so far we have shown we can more than compete here.
“So build on that, believe in that, work hard, be positive, improve.
“We have to improve because this is the Premier League.
“But if we do those things we have a real chance of staying in the division.”
