The Belgium worldwide has made a flying start to his career at Old Trafford with four goals in his first four competitive games, and ahead of a tricky Premier League trip to Stoke on Saturday and the start of the Champions League next week, he says he can handle the responsibility of being the club's main goal scorer.
But the 24-year-old former Everton and Chelsea striker is not shirking from the challenge that Ibrahimovic will pose to his starting spot.
United face Stoke City in their fourth Premier League game of the season on Saturday.
But the ex-PSG superstar has put them on the back-burner to focus on recovering from his ACL injury, which has kept him out since last season.
The England global is delighted with the way Lukaku has settled into the team and admitted to being flattered at being compared to Dwight Yorke and Andy Cole, who created a fearsome strike partnership in United's treble-winning campaign of 1998-99. Lukaku believes the veteran's experience and character will benefit the team.
Manchester United do need Ibrahimovic, any club in the world would be happy to sign him despite his age and the serious injuries that he is coming off. That's what we want at Manchester United. Ibrahimovic will know himself that he will not be the main player of the team like last season, and that his role will not be as vital.
The powerful striker has had to come back stronger than ever before, with this possibly his worst injury during his career.
