In recent years he has worked his way into the Brazil worldwide set up and was last month named in manager Tite's 23-man squad for this summer's World Cup in Russian Federation. The 25-year old has also featured in the UEFA Champions League being a vital player for his manager Paulo Fonseca, as Shakhtar Donetsk reached the rounds of 16 from a pretty hard group featuring Manchester City, Napoli and Feyenoord.
Willian said he has given advice to Fred about playing in England but insists both men are fully focused on the World Cup ahead of their country's final warm-up friendly against Austria on Sunday.
Many star players have struggled to shine straightaway in English football, even at United with Victor Lindelof and Henrikh Mkhitaryan recent examples.
The deal is expected to be in the range of £50 million.
The newspaper says United have agreed a deal worth around £52m including various performance-based add ons and Fred was all-set to be unveiled as their first major signing of the summer.
And in Fred he is getting a pocket dynamo - a stocky, left-footed box-to-box midfielder who can do a bit of everything, tackle, score, create and run.
He's also been dubbed "the new Fernandinho" which, if true, means United have a very talented player on their hands. But I'm glad that I could play the last four matches. Earlier in the year, Manchester City made a bid for the player. "Now I am focused on the national team and the World Cup and I am ready for it". The board of the Ukrainian club kicked its feet and refused to sell the player.
Fred also helped Shakhtar reach the Champions League knockout stages in 2017-18.
