VIDEO: Lionel Messi doesn't appreciate Kaka touching his head

Brazil defeated old rival Argentina 2-0 on Friday in a friendly match - that was friendly in name only - in Beijing.

While both team's marquee superstars were on the pitch, neither Lionel Messi nor Neymar could make a decisive impact on the contest. The Argentine actually missed a first-half penalty, and the two men were overshadowed by Diego Tardelli, who scored both goals for Brazil in the win.

In fact, Messi's best contribution was this quasi-snub on Kaka, who came over at the final whistle to greet the Barcelona superstar. It wasn't exactly a complete shunting, but it's clear from his reaction that Messi isn't pleased with the invasion of his personal space.

Don't mess with the flow, dude.
