Brazil and Argentina's finest have not disappointed.
Lionel Messi added two more goals to his World Cup tally, scoring at the beginning and end of the first half against Nigeria to put his total at four, matching Neymar atop the competition's Golden Boot standings.
In the third minute, Messi pounced on a rebound off a shot from Angel di Maria, hitting a thundering volley into the back of the net. Nigeria's Ahmed Musa followed with a great goal of his own a minute later, but Messi ensured Argentina had the lead going into halftime. Just before the break, Messi, who turned 27 on Tuesday, turned in a perfect free kick, bending a left-footed strike from long range into the upper right-hand corner to give Argentina a 2-1 lead. The sides traded goals rapidly in the second half as well, with Argentina holding on to a 3-2 win and cementing first place in Group F. Both sides are through to the final 16.
