Not sure if you respect Van Gaal's opinion but I just read that he rated him as the best player on the pitch. In a world cup semi final. Oh, and think about who else was on the pitch.
Not much if he comes out with rubbish like that.

The stats seems to correlate with the successful manager's opinion:
Ron Vlaar By Numbers:
100% tackles won
100% aerial duels
11 clearances
6 interceptions
92% pass accuracy

Average AT BEST though, yeah?
Edit - I know his stats are warped by playing against jokers like Messi, Aguero, Lavezzi and Higuain but even if he was playing against someone half decent he'd have done better than AVERAGE IMHO.
