Following his side's triumph, Van Gaal has said that there is no need to take a few days off before beginning his new role in England.
"That is no problem for me, I don't need a holiday," van Gaal is quoted as saying by thesportreview.com. "It's great to have such an exciting challenge.
"To work daily with young people is something that I don't need time off to rest for.
"I'm looking forward to it. I've only met two people from the daily management at the club – the chief scout and the chief executive officer. And I've met two of the owners. It's time that I get to know more people at the club."
Van Gaal has previously managed Ajax, Barcelona and Bayern Munich.
