Sir Alex Ferguson's men defeated Newcastle 3-0 on Sunday, with two goals from corners in the first half followed by a long-range effort from Tom Cleverley after the break.
And, after the former Everton attacker was deployed in a deeper midfield role on Sunday, he was keen to underline his commitment to doing a job for the team.
"You’re involved in the game throughout and I’m not one who won’t put the work in," he told Sky Sports. "I’ll put the work in and try and give my best for the team, and that’s all I can do.
"[I'm] not at all [concerned by not scoring], as long as we keep winning. We’ve got players who can score goals for us as well as myself.

The Croxteth-born forward went on to hail his side's defensive efforts in posting victory against Alan Pardew's side.
"The first six games of the season we haven’t defended well enough and that’s not just the back four, it’s the whole team. I think today we were brilliant; they’re a big physical team," he added.
"We knew we had to defend our box really well and we managed to do that and score three goals. It was a focused performance today and we need to continue to do that for the rest of the season if we want to be successful."
