I try to help the team and try to do what I'm best at.
Ibrahimovic went through a hard spell in September and October but the 35-year-old has been in prolific form either side of Christmas to take his tally to 13 goals in 19 games in his first Premier League season.
"I have no individual targets because that I did already after three months in England".
United, who are sixth in the Premier League, host second-placed Liverpool at Old Trafford.
"I have no problem [with the criticism] because I went through this my whole career, this is something that triggers me, gives me energy", Ibrahimovic told Sky Sports.
United won five and drew another of those six games, with Ibrahimovic's league tally now up to 13 for the season, just one behind Chelsea's Diego Costa at the top of the scoring charts.
Alas, Ibrahimovic has been a major success thus far, notching 18 goals in all competitions for Man United, while playing regularly despite his age.More news: FBI Director's Actions Surrounding Election Face Independent Review
"I choose not, I took the challenge, accepted the challenge, and that is what I chose".
"We had our dips, our ups and downs".
"I'm just looking forward to reaching out and gaining new fans, for myself and for this team".
Both sides need a win to maintain any faint hopes of pipping Chelsea to the title and as with nearly every Man United-Liverpool game, we should expect some drama.
"The last one-and-a-half months have shown the right way, the gap [at the top] has been bigger but now it's better".
"Whatever you want, wherever you will come, let's see what we want".
Come come now Mr Ibrahimovic, you've conquered nothing yet.
