However, last season too they were very impressive up front and it was due to the efforts of one man in particular, and it is a player that Jose Mourinho feels will return before the curtain falls on 2017.
Jose Mourinho says he "feels" Ibrahimovic might be back before the end of 2017.
Zlatan Ibrahimović was instrumental in the Red Devil's attacking prowess since his signing and his 28 goals until he was ruled out by injury was a sight to relish.
Providing a fresh update on the situation during a press conference held before Saturday's (21 October) Premier League trip to Huddersfield Town, Mourinho confirmed that the 36-year-old was indeed working tirelessly at United's Carrington training base and claimed to have a hunch that he will return to the pitch before the end of December.
"Zlatan is here, he's working here, he's under our control".
Earlier this week, Ibrahimovic returned to team training for the first time and is reportedly only a couple of weeks of participating in full sessions. "Yes I do. But it is just a feeling".
Andy Cole told MUTV that he hopes Ibrahimovic will return to the fray over the winter period.
Mourinho has said in the past Ibrahimovic would not be back until the New Year.
"It's just then a question of the way you position yourself in relation to that, the way you think is best way you think is to do it".
On United's general injury situation, he said: "The injury process normally is a process of some guys get injured, some guys recover from injury, unless we lose completely the balance, this happens to nearly every team". It is better to remember that player A or B is missing, and player C or D is so important for the team. I think he is looking forward to coming back, most probably in December or January time.
"The way we try to do it is always to speak about opportunities for others".
