In the 32nd-minute, Paraguayan defender Omar Alderete got a yellow card. Five minutes later during a counter-attack, he brought down Messi to the ground, but the referee ignored it, not handing a second yellow. At the end of first-half, Messi confronted the referee and could be seen pointing his finger at him. Then another incident when Messi attempted to take a corner, but was targeted by Paraguay fans, who threw bottles at him.
