Muamba was one of England Under-21s' top performers in the summer as Stuart Pearce's men surged to the European Championship final.
Muamba, 21, still has aspirations of breaking into the full England set-up before Fabio Capello names his squad for South Africa.
Muamba said: "I never get jealous of the boys who have stepped up to the full set-up. They have done extremely well to get up there.
"It just goes to show that if you are playing well, Mr Capello is willing to give everybody a chance and it's great they've done that.
