He played average in both.
Messi ran more, I'll give you thatSo all in football is about goals?
In my opinion, Messi played much better in WC'10 than in WC'14. But in 2014 he scored 4 goals and in 2010 none.
The fact that he didn't score any goal in 2010 was pure [bad] luck, added to the fact that he played in midfield under Maradona.
But that has nothing to do with you, Diego. Messi arrived in much better form to SouthAfrica than to Brazil. Simple as that.
