Lionel Messi and his Argentina teammates were fooled by a pitch invader, who resembled Brazil star Ronaldinho, at their training session at Belo Horizonte's Estadio Independencia.
Messi and Co. were Wednesday preparing for their opening group game against Bosnia Sunday when the intruder wearing a Atletico Miniero jersey, Ronaldinho's club, interrupted proceedings, reports Goal.com.
The Argentine team were taken by surprise and were seen laughing before the fan was whisked away by security officials.
This was not the first and nor the last incident. More than a dozen fans invaded the pitch with one kneeling down in front of Messi and shining the Argentine captain's boots.
Argentina also play Iran and Nigeria in Group F.
