Not even Wensleydale?
At the end Van Persie really couldn't go on playing or at least he wasn't able to receive the ball well/participate in attacks. He had been sick for a few days and apparently wasn't that fit yet. Van Gaal also wanted to win the match before penalties came. That's why he brought Huntelaar (and therefore Krul was not possible).
Cillessen has been a strong goalkeeper throughout the whole tournament but he really has trouble with penalties. In fact, he has never stopped one, ever.
I am curious how the next coach, Guus Hiddink, will look at this "problem".
Well, naturally, I am very disappointed about all this. Now let the Germans win.
Yep, they said that in the commentary over here (that Cillessen had never stopped a penalty in his professional career), which I found quite incredible. And after learning that fact, it became more obvious to me why Van Gaal went with Krul in the previous match for penalties. It seems also, that it was intention to do the same thing in the Argentina match:
"If I could have substituted Jasper, I would have done, but I'd already used three substitutes so couldn't do that. I subbed Janmaat for Indi because he had a yellow card already and was often too late and wasn't executing well. I didn’t want to take a risk on Nigel de Jong being injured and he was the free man in midfield and Clasie can play going forward better than Nigel. I subbed van Persie because he was exhausted."
