Louis van Gaal has been sacked as manager of Manchester United, with former Chelsea boss Jose Mourinho set to be named as his replacement.

The Dutchman leaves after completing two years of a three-year contract.

BBC Sport reported on Saturday that United's FA Cup win over Crystal Palace would be his last game in charge.

Mourinho's appointment is expected to be confirmed after the 53-year-old Portuguese meets with senior United officials on Tuesday.

"In April 2014, United's mishandling of the sacking of Moyes was heavily criticised, the coach humiliated when learning of his demise through the media.

"The club's hierachy accepted it was wrong that news had leaked out before the manager had been informed. But two years on, it has happened again.

"Van Gaal was apparently informed of his impending departure by his wife when - still at Wembley following the club's FA Cup Final win - she read the news on the BBC website on Saturday evening.

"United hold the Dutchman in high regard and had desperately tried to maintain secrecy during their negotiations with Mourinho, hoping Van Gaal would lead his team to a top-four spot in the Premier League.

"Even after that target was missed, the club wanted him to be able to enjoy his FA Cup win, never once briefing against their coach or adding to the speculation. But it was always naive to think that news of their plans would remain secret.

"Once the news broke on Saturday, it was hard to fathom why they waited to put Van Gaal out of his misery. Once again serious questions will be asked about the way the Glazer regime runs the club - and the way it communicates."

Van Gaal, 64, took control of United after leading the Netherlands to the semi-finals of the 2014 World Cup finals in Brazil.

The Old Trafford club finished fourth in the Premier League in his first season in charge to qualify for the Champions League.

But they finished fifth this term and will play in the Europa League next season.

They only scored 49 league goals, too, their lowest total since 1989-90.

Saturday's FA Cup success at Wembley gave United a first trophy since Sir Alex Ferguson delivered the Premier League title in 2013 in his last season before retirement.

But it was not enough to stop Van Gaal from losing his job.

Mourinho, 53, was sacked by Chelsea last December, just seven months after leading the London club to the Premier League title.

How do the stats shape up?

•     Manchester United scored 49 Premier League goals this season - one more than Blackburn scored when they were relegated in 2012
•     For the second consecutive season, United ended up with a negative goal difference away from home
•     Went 11 home games without scoring a first-half goal earlier this season
•     They conceded the joint fewest goals in the league - 35 - along with Tottenham
•     The team made 3,222 backwards passes - the most in the league
•     Van Gaal used 33 players over the season - the second highest number after Liverpool (34)
•     Man Utd topped the clean sheet record table alongside Arsenal with 18

What is his legacy?

Van Gaal arrived at Old Trafford with his reputation enhanced after steering the Netherlands to the 2014 World Cup semi-finals.

The experience he gained while managing Ajax, Barcelona and Bayern Munich also suggested he had the necessary clout and ego to succeed at United, in contrast to predecessor Moyes, who had been in charge at Preston and Everton before taking over at the end of the 2013 season when Sir Alex Ferguson retired.

After a solid first season, Van Gaal was expected to turn United into title contenders, especially after taking the club's outlay on players to more than £250m since the summer of 2014.

His record in the transfer market has been hit and miss.

Angel di Maria - a British record signing at £59.7m - faded after a fast start and was sold, while Radamel Falcao delivered little after his loan move from Monaco.

The summer of 2015 has hardly proved a success either, with Bastian Schweinsteiger and Morgan Schneiderlin, who reportedly cost United a combined total of around £40m, failing to add dynamism to midfield.

This campaign has also been undermined by injuries, with Luke Shaw, Antonio Valencia, Marcus Rojo, Schweinsteiger, Wayne Rooney, Michael Carrick, Phil Jones and Ashley Young all missing significant parts of the season.

What did his critics say?

A number of significant former United players have taken issue with the style of play under Van Gaal, claiming his tactics are negative and players are afraid to express themselves.

"Manchester United are going backwards again and I don't see that changing because the manager will not change [his tactics]," said Rio Ferdinand, the England defender signed for a then British record £30m in 2002.

Steve Coppell, who starred for United in the 1970s and 80s, said it was hard to understand Van Gaal's philosophy, claiming "players sometimes do not really understand what he's trying to get through to them".

Former midfielder Paul Scholes - a member of the club's legendary 'Class of '92' - was one of the Dutchman's harshest critics.

"It seems he doesn't want players to beat men and score goals," he said. "It's not a team I would have enjoyed playing in.

"There's no spirit, there's nobody having a go at each other, there's no smiling, there's no entertainment."
