The Swede ended a run of six matches without a goal by scoring twice in Sunday's win at Swansea - his first Premier League goals since finding the net against Manchester City on September 10.
And, while he knows he could have added a few more to his tally, the 35-year-old is happy with how his first season in English football is going.
"I think I could have scored a couple more goals than I have done," he told Inside United.
"I missed pretty good chances which I didn't see myself doing but it's a different game here.
"With my performance, I am happy
I know I can do more, I know the team can do more and I want to do more and I will do more."
United's performances have also been patchy, with the win at the Liberty Stadium their first in five league matches which, combined with the EFL Cup and Europa League defeats to Chelsea and Fenerbahce respectively, has led to questions being asked about United's quality.
But Ibrahimovic is confident they will get it right.
"It will click," he said
"We just wait for the moment when everything is clicking among each other, not only inside the pitch, but outside it.
"I don't say things are bad because things are good
We've been a little unlucky in certain games but we believe and, when you believe, it will come.
"I like to train hard, that's my philosophy
If you train hard, you get what you want to get
Hard work pays back, according to me..
and it does after 20 years of experience."
