United are gunning for a spot in the top four of the Premier League, battling with the likes of Tottenham, Chelsea and Arsenal.
Solskjaer’s arrival has given them a fighting chance after rejuvenating the squad following the gloomy days of Jose Mourinho.
Under the Portuguese manager, several players had seen their progress stunted including Fred – who had only just made the switch to Old Trafford last summer.
The Brazilian joined from Shakhtar for around £50m but has failed to make an impact for much of the season.
But in recent weeks the 26-year-old has seen his performances improve with displays against Paris St-Germain, Barcelona and West Ham being praised by fans and pundits.
Solskjaer as placed more faith in the midfielder and has even compared his woes to another star that initially struggled for form.
He said:”It’s always difficult to come here. One: It’s Man Utd, you’re expected to perform straight away. Two: It’s an English league that he’s not used to.
“But he’s a Brazilian international, Andreas is a Brazilian international, the talent is there and when they get the chance the next time it’s easier to come into a team that’s doing well.
“There’s loads of players that have come in and found the first few months difficult. One of the best players I’ve played with that struggled the most was Diego Forlan.
“Veron [is another] you know, those two fantastic players and it took a bit of time. But when they settled they performed.
“So I don’t think he needs to worry too much. He’ll get chances.”
United mounted an incredible comeback against PSG in the Champions League at the Parc des Princes last month after winning 3-1.
And Solskjaer credited Fred as one of the top stars on that day.
He said:”That was probably Fred’s breakthrough for us.
“You can see why we signed him. He’s got the mentality of a Brazilian international, he is a Brazilian international, he gets on the ball, no fear, no doubt whatsoever.
“And we played a system today he used to play at Shakhtar and that’s why we signed him.”
