The Daily Mail is reporting that United have agreed personal terms with the 22-year-old and his father of around £90,000 a week and that the two clubs have all but agreed on the deal.
Sir Alex Ferguson is a big fan of Thiago and United had a £15m bid for the midfielder turned down in 2011. After that bid, Thiago signed a new deal at Barca, but it included a playing time clause, which is why he is available at the moment for only £17m.
After being unable to persuade Cesc Fabregas to leave the Camp Nou for Old Trafford this summer, United then turned their attention to Thiago and got a player who I believe can be as good as, if not better, than Fabregas at a fraction of the price that Fabregas would have cost.
Thiago, along with 23-year-old Tom Cleverley gives United a potential midfield partnership for the next decade. Add in 24-year-old Shinji Kagawa who has really impressed in the Confederations Cup and United have three talented young playmakers to build the side around for the next decade.
