The former Sweden international moved to the Red Devils in a free transfer from Ligue 1 champions Paris Saint-Germain in the summer following the appointment of Jose Mourinho in May.
The Red Devils have made good progress in the cup competitions in recent weeks after a 3-2 aggregate win against Hull City in the EFL Cup semi-final and a 4-0 victory over Wigan Athletic in the FA Cup fourth round.
Ibrahimovic was rest for both of those games after the 35-year-old striker scored 14 times in his opening 21 games in the 2016-17 Premier League campaign so far.
The ex-Barcelona and Inter Milan centre-forward has also found the net four times in the cup competitions.
Speaking to Sky Sports about Manchester United’s lack of activity in the January transfer window, Nicholas accused the Red Devils of being too reliant on Ibrahimovic.
“They spent big in the summer. Has Jose Mourinho got it right? The structure and organisation is there but I don’t think they’re exciting. They’re too reliant on Zlatan Ibrahimovic. I’m not surprised that Wayne Rooney is staying put but I expect him to go at the end of the season,” Nicholas said.
Manchester United will take on Southampton in the EFL Cup final at Wembley.
