He is totally in the game, which is putting him in a position that he has everything to become a really, really good player.
Speaking to journalists after the game he said: "I could have asked for more. I spoke with him, he's a great lad. he's doing a job of course".
Further goals could have been scored in the opening stages as the Premier League side dominated possession and attacked purposefully.
"He's injury free and is willing to train and play well for West Ham United". That will come with confidence, with maintaining that pattern, and with points.
Despite all the big names, Bilic did reveal that Andy Carroll would be rested for the clash, while three others have been ruled out with an injury. He looks good, he looks fit, he is training, hopefully he is going to last because that was his problem for ages.
"We are managing him a little bit differently this year".
"He isn't going to play [on] Tuesday, for example". We would need a few top performances, and you are talking about three, four games, it's not a league. "We had many chances to score more goals, but we played very solidly and we can progress like that", Arnautovic said.
"We didn't let them have any chances, we played solidly and we showed good personality and this is the most important thing".
He told the press ahead of the Bolton game: "Of course, we are very ambitious and of course we are thinking about the cup in a positive way".
