The Dutchman's polarising reign at Old Trafford has been cut short amid intense speculation that Jose Mourinho has been lined up as his replacement Manchester United have sacked manager Louis van Gaal, Old Trafford sources have informed Goal. The Dutchman led United to their first FA Cup triumph since 2004 on Saturday, with a 2-1 win over Crystal Palace, though celebrations were quickly overshadowed by speculation regarding Jose Mourinho's imminent arrival. Van Gaal's two-year reign at Old Trafford proved divisive, with several fans and former players bemused by the Dutchman's playing style having seen United score just 49 league goals this season. And after Van Gaal arrived at the club's Carrington training ground for work on Monday he was relieved of his duties. The 64-year-old remained cordial throughout the rest of the morning but his backroom staff were seen clearing their desks after being sacked along with the man who brought them to the club in 2014. Executive vice-chairman Ed Woodward was also seen on site alongside one of the club's lawyer.
