Fred joined the Ukrainian giants back in 2013 from Internacional, since then he has featured regularly for them and helped them clinch 2 domestic league titles, two domestic cups and two super cups.
The club announced on Tuesday that it had reached an agreement with the 25-year-old and the deal is expected to be completed this week.
At around 5 ft 7 inches, Fred is a dynamic box to box midfielder who should improve United's tempo going forward.
With the signing of Fred all but confirmed, Manchester United are off to a very positive start with regards to their summer transfer dealings.
Manchester United manager, Jose Mourinho, has predicted that the Super Eagles of Nigeria will qualify in Group D at the 2018 World Cup in Russian Federation.

Manchester United boss, Jose Mourinho had spoken of a Brazilian arriving at Old Trafford in the coming season, insisting that every team needs the flair and finesse of a Brazilian.
Instead, the most likely scenario will be Pogba lining up in his favoured left-sided central midfield role with Fred on the right and Nemanja Matic sitting in between them.
"It's very hard, I don't want to be emotional but I have to be", said Mourinho.
"Fred is a really good player", says Dmitry Nedaivozov, who heads Shakhtar's London Supporters' club, "though I'm not sure he is good enough to be a Man U player".
"He is a wonderful player", the former world footballer of the year said.
