Opening it in style
The Hammers came into this curtain raiser on the back foot, having been defeated 2-1 in their first-leg of their Europa League qualifier.
However they opened the Olympic Stadium in the best fashion, with goals from Cheikhou Kouyate and Sofiane Feghouli giving them the 3-0 win, and Bilic shared his delight at the win.
He told whufc.com: "It was a special kind of game for us, the first game at the new Stadium" and believes they "played good football. It was totally different to the game in Slovenia."
He continued: “We deserved it" as "we pushed and concentrated for the whole 90 minutes but 3-0 is a good result for us" and admitted "it’s important because it is in front of the crowd in the new Stadium. It was a good night for West Ham."
Bilic concluded: “We deserved it, played some good stuff and the crowd could enjoy some of our beautiful moves from the whole team."
Special night for the club

Nordtveit concluded: “Of course there's always some nerves but I think we were all quite sure that we had the quality to beat them at home" and believes "you always want to make a good start and this was a good start at the new Stadium."
