Fellaini's performances being central to the Blues' impressive attacking displays, the recently-capped England man says everyone needs to chip in.
He told evertontv: "It's always important to try and spread the goals, but at the same time you're going to get a period in the season where it's tough and you need your players playing up the pitch to score the goals. Felli's certainly been doing that for us lately.
"He's a massive player for us at the minute, that's evident in the way he's playing and the way we play.
"We're not a one-man team, we've got a number of good players this year. I think it's shown in our football this year how we're developing as a team and that we're becoming a better footballing team."
