Jose Mourinho will be confirmed as the new Manchester United manager next week.
According to BBC Sport, United struck a deal with the former Chelsea manager prior to the club's FA Cup-winning victory over Crystal Palace on Saturday 21 May.
The club will announce Louis van Gaal's departure early next week before officially appointing the 54-year-old Portuguese. Mourinho has been out of work since December 2015 after being sacked by Chelsea.
While he celebrated FA Cup success on Saturday, van Gaal's position at the club has been under severe scrutiny throughout the season. The former Ajax, Barcelona and Bayern Munich manager has been widely tipped to lose his job after the club's failure to qualify for next season's Champions League was confirmed.
The Dutchman was named David Moyes' successor at Old Trafford in May 2014, signing a three-year contract at Old Trafford. Despite spending in the excess of £250m in the transfer market, United's lack of progression during his tenure has been alarming.
Despite losing nine of Chelsea's opening 16 games last season, Mourinho will arrive at United with his reputation as one of the game's most revered managers intact.
The former Porto, Inter and Real Madrid boss has won league titles in four countries, winning the Champions League twice during his spells in Portugal and Italy.
