Manchester United have been urged to show patience with Jose Mourinho by Mark Bosnich, with the club's former goalkeeper telling the Red Devils not to be drawn into regular changes like rivals Liverpool.
That came a campaign after Mourinho led United to a Europa League and EFL Cup double.
Bosnich, who had two spells at United, says the Portuguese tactician needs more time and the club should avoid following Liverpool's lead, the Merseyside giants having made numerous changes in their bid to win a first league title since 1990.
"Just stand by him [Mourinho]. Give him the opportunity, he is second against a team in Man City who can afford anyone and get anything," he told Omnisport and Goal.
"Sometimes, even after such dominance, you have got to be patient.
"You don't want to fall in a situation like Liverpool, after all those years of dominance and then all of a sudden you want to chop and change.
"Stick with this guy, he is a winner and he will bring the glorious times back.
"People can say what they want. In modern-day football, after we saw the experience with Barcelona, that started with Pep Guardiola, out of something good can come something bad, and vice-versa.
"But, after that, just like after the Leicester thing with chairman saying 'well why can’t we do that', we saw a lot of people say 'why can’t we play like that?' So, I think a lot of teams suffer for the comparison, that’s one of the greatest club sides that anyone has ever seen playing in a way that no one has ever seen before."
Bosnich recalled similar impatience at United under the great Sir Alex Ferguson, who led the club to 13 league titles in 27 years.
The former Australia international believes Ferguson's tale is a reminder that managers need backing.
"What everyone has got to realise is that not last season but the season before, they won three trophies [United also won the Community Shield]. That is an amazing achievement no matter where you are at," Bosnich said of Mourinho's United.
"This season? Okay, no trophies but far more points than last season and in second place. It takes time.
"People have short memories. I was at Manchester United in 1990, I think Fergie had only been there for four years, there was a game against Crystal Palace in the season that they won the FA Cup. Half the crowd sat down because he left Mark Hughes on the bench. They were calling for 'Fergie out'.
"He went onto win the FA Cup, ironically against Crystal Palace that year. The rest, as they say, is history."
