The two great rivals will meet in Miami later today.
Responding to comments by Liverpool boss Brendan Rodgers that he will find the competitive nature of the Premier League very different to working at Ajax, Barcelona and Bayern Munich where the league is dominated by one or two clubs, Van Gaal replied: "That's why I'm here.
"Okay, maybe he is right because I have to experience that but I was also in Spain and in my first year and I won three titles, in Germany I won two titles. If I win one here we will all be happy."
