However, Sneijder, who has scored twice in 17 outings for Turkish Super Lig giants Galatasaray this season, has revealed that as good as Van Gaal is as a football trainer and coach, his man-management skills have been despicable and that’s the area the pair have clashed in the past.
“I have always said that Van Gaal is the best coach there is, technically and tactically,” the 32-year-old Netherlands international who worked with Van Gaal at the 2014 World Cup in Brazil where they finished as third-place winners told Fox Sports.
“There is no better coach than Van Gaal. But I think there is room for improvement when you look at the way he deals with his players and staff.
“I had a perfect time with him on the pitch, as a coach, because his training sessions were the most fun.
“But as a human being, I have had nothing but trouble with him on a personal level.”
Sneijder was at Ajax when Van Gaal was appointed sporting director at the Amsterdam club in 2004, before they were reunited with the Dutch national team in 2012 and 2014.
Meanwhile, Sneijder will be looking to inspire Galatasaray to move up the table when they visit Konyaspor at the Torku Arena on January 15.
Gala currently sit third in the Turkish Super Lig behind surprise leaders Istanbul Basaksehir who were playing amateur football just 26 years ago.
