The Dutchman also revealed he had turned down the opportunity to coach struggling Spanish club Valencia last month. "Whether I continue or not will also depend on the offers I get," he added. "I've coached many clubs and I think it's very difficult to improve on that level of clubs. "It's not true that I've retired, not at this moment, but I'll decide at the end of my sabbatical, next June or July."
Van Gaal won seven national titles with Ajax, Barcelona, Bayern Munich and AZ before being appointed Manchester United boss in May 2014. He guided the Red Devils to the FA Cup, as well as a fifth-place finish in the Premier League, before being replaced by Jose Mourinho.
