It is also being reported that the Premier League club and the player have already agreed on a salary for the central midfielder of about £182,000 per week.
Vidal had earlier confessed to his friends at Turin that he is willing to take up on the United offer and that he will leave Italy for England.
The official deal is yet to be made for the Chilean and talks have suggested that a five-year deal is agreed between the player’s agent and the authorities at Manchester United.
If and when the deal goes through, Vidal will spearhead the Manchester club’s midfield easily as a first choice player with players like Michael Carrick and Darren Fletcher among others being circulated to partner him ahead of the defensive line.
