West Ham finished seventh in Bilic's first season in charge, but a move to London Stadium and the loss of influential playmaker Dimitri Payet to Marseille have contributed to a difficult second term. Bilic said: "Well it was a hard season, but every season is hard. I consider this season as a great season for me individually for the team and club. "This season we experience negative things, we moved the stadium, the training ground, a very strange pre-season. And then we were hit of lots of injuries, some positions we didn't have any players. "To come out of that in such a good way, of course we want to improve but it looks pretty good now. It makes you stronger. It's different if you are eighth, ninth and 10th and stay there. This way you enjoy it and it gives you more experience for the future." West Ham face Premier League leaders Chelsea on Monday, having knocked them out of the EFL Cup in October. And Bilic is a fan of Blues boss Antonio Conte. He said: "I'm surprised how good they have been. I was expecting him to have a strong impact because he had it at Juventus. "I watched Juve quite a lot and I was studying his game. I didn't know because no-one knows. "I expected him to do great long term and it is a surprise they are 10 points clear. Conte is a great manager, he done it at Juve, he done it with Italy. A brilliant manager of course. "The title race is still very open. Many, many points. If they slip up, which you can in every game, other teams need to be ready."
