Mourinho was under heavy pressure at Old Trafford a few weeks ago after the start of the disappointment.
This pressure seems easy with Manchester United as it has had a few positive results, including Juventus's victory in the middle of the week.
It is featured in the starring role of Anthony Martial and Marcus Rashford when Juan Mata made a United-level free kick in the tournament.
Footballer Romelu Lukaku failed from the Juventus team with the hurting uncertainty factors of whether he would fit the current derby with Manchester City.
And when Vidic knew that United lost through the transition in recent years, he believes that things are now on the rise.
"It's very difficult," Vidic said to beIN Sports.
"Of course, we knew it would be very difficult when Sir Alex Ferguson left.
"He won many prizes and he has such a big personality in that club.
"But we are still waiting, even if we do not win prizes, be much closer to the trophies.
"I believe that in the last games, I think they have started to be more positive, as Mourinho did according to his team-mate.
"Martial, Rashford, Mata front … It's time for football.
"I want to see it."
Although Vidic sees positive, puppies Jennifer Jenas thinks Manchester United is still struggling.
"Sir Alex United is not currently with United, and you do not see current performances through the former team's achievements and style," Jenas wrote in Mail.
"This club is more like Liverpool in the 90's, according to Roy Evans and Gerard Houllier.
"Take the result against Juventus on Wednesday night, Jose Mourinho's masterpiece and probably the best performance he received.
"It was classic Mourinho: no one gave him a chance, the crowd was against him, the team he had played had proven to be better at Old Trafford, many people wanted to lose.
"He loves the beast, he is still at his best when he has to be a reactive coach who wants to steal the result instead of being a superior favorite and asking for a great football.
"And at this moment United is at the moment."
