Jose Mourinho has asked all the attackers at Manchester United to do more in front of goal, especially Rooney, to lift the burden of finding the net on Ibrahimovic.
The England captain has just three goals in 20 appearances in all competitions and failed to find the net in the 2-0 win over Zorya on Thursday.
The Red Devils have only scored 19 goals so far this season, with Ibrahimovic scoring eight of those.
Red Devils manager Mourinho wants a better return from Rooney, who needs just one more goal to equal Bobby Charlton’s all-time goalscoring record at United, but says the onus is not just on the England skipper.
“As an attacking player, normally Rooney scores more goals,” Mourinho told reporters.
“He has scored a couple, I think, at Fenerbahce and one in the Premier League. We expect more goals from him, yes.
“But we expect more goals from everyone in the team.
“Maybe Zlatan is the one, but as the main striker it is normal that he has scored more goals.
“But we expect more goals from all the other attacking players.”
Rooney has often been used in a deeper role for England, but Mourinho maintains he will not be following suit at Old Trafford.
“With me, he is an attacking player,” he added.
“In the national team, they can do with him what they want to do. In the national team he is their player, he is not my player, and they can do what they want. If they want to play him right-back, they can play him right-back. It’s not my problem.
“But in my team, he is an attacking player. He will play as a nine or a 10, or eventually coming from one of the sides.”
