To be honest, mate, I don't. However, you can't make a managerial appointment on the hypothesis that Holland won't progress in the tournament. On one hand, best scenario for us would be for Holland to get knocked out in the groups, but does that bode well for van Gaal at United? I personally wouldn't be happy with that.
On the other side of the coin, in order to cement his status as a great coach, he'd lead Holland into the latter stages of the tournament, but as a result, misses the entire pre-season of United and doesn't get time to analyse our squad, decide who he wants out, who he wants to sign etc. and we begin the season in dire straits. We cannot afford to make the same mistakes - as a club - that we made last July and August.
Can you see where I'm coming from with this? van Gaal's World Cup commitments are just an unnecessary distraction and I think it's a major blot against him.
