Van Gaal was sacked by Manchester United to make way for Jose Mourinho last summer.
The Dutchman was often criticised during his two-year stint at Old Trafford, with fans despairing at his style of football.
However, he did bow out by winning the FA Cup – the first time the club had won the trophy since 2004.
Van Gaal’s time at United was one of disappointment given how expectations had soared after Holland’s 2014 World Cup campaign.
The Oranje finished third in Brazil despite few giving them a chance of competing with the big boys.

Wijnaldum believes Jurgen Klopp is the better manager but says he loved playing under Van Gaal for his country.
“His courses were delicious. But Klopp I work every day.
“They are both honest, they really love their players.
“You can feel it. Van Gaal was fantastic.
“During the 2014 World Cup in Brazil, he called me to him. ‘Gini, I want you in a supervisory role to give a starting spot,’ he said. ‘Danny Blind says you can. I personally think you can not.’”

When asked if it was a little too honest, Wijnaldum said he had no problem with Van Gaal’s blunt style of management.
“Why? I liked it, he said exactly what he thought,” the Liverpool ace added.
“And you could also like to discuss with him, he was never angry.
“That World Cup in Brazil was a unique experience. For the game with her third place against the Brazilians, he called me again.
‘It's time to score again,’ he said. And it worked.
“I was there later on with Leroy Fer. We grew up together, are true friends. We both scored in the final round of the World Cup, which gives a wonderful feeling.”
