Fred is now expected to complete the formalities of the move and become a United player before heading off to Russian Federation for the World Cup where he's due to play a key role for Brazil in their group games against Switzerland, Costa Rica and Serbia.
Sources have told ESPN FC the deal for the 25-year-old is worth around €55 million, which could rise to €60m with add-ons.
The speed of United's pursuit, though, has been striking and they have capitalised on the fact that both the player and Brazil coach Tite want the transfer to go through before the World Cup starts in Russian Federation next week.
Fred made his senior debut for Internacional in 2012 before moving to Shakhtar in 2013.
It appears those reports are accurate as United have now released a statement on ManUtd.com confirming an agreement has been reached with Shakhtar for the signature of Fred. He played in wins over Manchester City and Napoli, scoring in a 2-1 win over Roma in the last 16.
In December 2015, he was given a one-year ban after testing positive for a banned diuretic, which was backdated to June that year when the test was carried out.
Lucescu said of his imminent arrival at Old Trafford: "I'm really pleased Fred has completed his transfer to Manchester United, I am proud of him".
United are getting a little, stocky, left-footed midfielder who will bring real dynamism.
