He will work on it, he's with special players and he's with Mourinho.
Lukaku was signed for £75m from Everton and has 3 league goals in 2 matches, but Mourinho wants Zlatan to be signed to offer title-winning experience to his team and also help Lukaku to be better.
He scored 28 goals in all competitions for United last season and was a huge influence in the dressing room so I'm sure he'll be a welcome addition to the squad at Old Trafford.
United boss Jose Mourinho has wanted him to sign a contract to stay at the club all along.
He missed more big chances than any other striker in the league last season and was lucky to retain his sacred place in the starting eleven as long as he did. They did, however, offer the Swede the opportunity to stay with them and undergo rehabilitation at Manchester United's Carrington complex - an opportunity that Zlatan was happy to take.More news: Power goes back-to-back at Pocono
It seems his speedy recovery has convinced United to re-sign the striker as the Mirror are citing a report from ESPN FC that claims Ibrahimovic is set to sign a contract and become a Man Utd player again by the end of this week.
Zlatan uploaded a video on social media on Sunday, showing himself working out and kicking with both feet, captioning the video, "which knee" which went to show that his injury is gradually becoming a thing of the past.
Zlatan Ibrahimovic shared this video on his Instagram account last night, with the caption "Which knee?", sending thousands of fans into an absolute frenzy, as he suggested that he's way ahead of schedule on his road to recovery.
For what pace Zlatan lacks in real-life, he certainly makes up for in this game.
