The Hammers have climbed into third place in the Premier League table, and they have already beaten the likes of Manchester City, Arsenal and Chelsea.
Bilic’s side's start has raised expectations at Upton Park, and the Croatian boss attributes their good form to the dedication of his players.
“It’s only a start, but we are confident and if we continue to work hard, like we have been from day one, I don’t see a reason why we should drop dramatically,” he said.
“There will be ups and downs with results, that’s football, but we are confident and we are gaining everything that is important: atmosphere, individual confidence, team bonding. Winning games is the best way of doing that.
“The reason we are doing well is the quality of the players, the team spirit, our pattern of working hard, we are respecting the opponents but not fearing them. It is down to hard work with individual responsibility. It is very enjoyable so far.”
Bilic has made a brilliant initial impression at Upton Park, with his tactics and personality immediately winning over the fans.
The Hammers support seems to be united behind their manager, and the club is riding the crest of a wave at the moment.
Whether they can keep their current performance levels up for the duration of the campaign remains to be seen, but they have proven the amount of quality that they have in their ranks already.
West Ham have only been outscored by Manchester City in the Premier League to date, and they go into their weekend match with Watford unbeaten in last seven league matches.
