Mourinho was under immense pressure at Old Trafford a few weeks ago following a disappointing start to the season.
That pressure seems to have eased with Manchester United having picked up a few positive results, including winning 2-1 at Juventus in midweek.
It’s come with the likes of Anthony Martial and Marcus Rashford starring while Juan Mata scored the free-kick that drew United level in Turin.
Striker Romelu Lukaku missed out against Juventus with injury with it unclear whether he will be fit for today’s derby with Manchester City.
And while Vidic knew United were going to go through a transitional phase in recent years, he believes things are now on the up.
“It’s very difficult,” Vidic said on beIN Sports.
“Of course we knew it was going to be very difficult when Sir Alex Ferguson leaves.
“He won many trophies and he’s such a big persona at that club.
“But we were still expecting, even if not winning the trophies, to be much closer to the trophies.
“I think in the last few games, what I like is they are starting to be more positive, including Mourinho in his team selection.
“Martial, Rashford, Mata up front… That’s pretty attacking football.
“I like to see that.”
While Vidic is seeing the positives, pundit Jermaine Jenas thinks Manchester United are still struggling.
“The United of Sir Alex doesn’t relate to the United of today and you cannot view current performances through the achievements and style of the former team,” Jenas wrote in the Mail.
“This club is more like Liverpool in the Nineties under Roy Evans and Gerard Houllier, a team adjusting to its loss of stature.
“Take the result against Juventus on Wednesday night, a masterclass from Jose Mourinho and probably the best performance since he took charge.
“It was classic Mourinho: no one gave him a chance; the crowd was against him; the team he was playing had been demonstrably better at Old Trafford; plenty of people wanted him to lose.
“He loves playing the villain. He’s still at his best when he has to be a reactive coach, relishing stealing a result rather than being overwhelming favourite and asked to play expansive football.
“And that’s where United are at the moment.”
