The 21-year-old has scored two goals in four appearances for the League One outfit so far this season.
Moncur told the Daily Star: “It’s hard going to a new team, especially when you do not know what is going to happen.
“I am a positive person, I look to the future and the next match in front of me and how I can affect it.
“Obviously I want to play for West Ham, but I also want to catch the eye of bigger teams, which is understandable.
“I really like playing here and enjoy it. But I am just going to play each game as it comes and see what happens when my loan is up in January.”
