"I think I'll retire. I actually wanted to quit after World Cup," van Gaal said while receiving a lifetime achievement award from the Netherlands government on Monday, as quoted by ESPN.
"After Manchester United, I thought I would stop, but then I later changed it to a smart sabbatical -- but now I do not think I will return to coaching.
"I could go (to China), but I am still here. So much has happened in my family, you become a human being again with your nose pressed to the facts," the former FC Barcelona and Bayern Munich coach said.
The 65-year-old spent two seasons at Manchester United after leading the Netherlands to a third-placed finish at the 2014 World Cup.
The Dutchman won the Champions League plus domestic league titles in Spain, Germany and Holland in a decorated career.
