Young guns against seasoned veterans; all-out attack versus watchful defence; two top-class keepers (Miguel Estrada and Diego) face to face with two opportunistic goalscorers (Ricardo Villalobos and Ricar). These are where the battle lines will almost certainly be drawn when Mexico and Uruguay put their hunger for glory to the test in the semi-finals on Saturday.
A low-scoring affair will almost certainly suit the Uruguayans although their opponents have shown an uncanny knack for striking when the time is right. Two key stats to bear in mind: of the four semi-finalists Uruguay have both conceded and scored the fewest goals (10 and 11 respectively), while Mexico have conceded the most along with Brazil (15).
With no suspension or injury problems hampering their preparations, both sides are expected to be at full strength.
Never before have the two sides met in Rio. This is Uruguay's second consecutive semi-final appearance following last year's spot-kick triumph over France. Mexico have also made history, becoming the first CONCACAF representative to reach this stage of the competition.
They're a defence-minded side and they don't tend to take too many risks. Although we're more ambitious and we can adapt to the demands of each game, we'll be sticking to our style: to attack and keep on attacking right till the end. Rather than changing our tactics, we'll get them to change theirs - Miguel Angel Estrada, Mexico keeper.
They might be short on experience but they're one of the sides who has progressed most since the qualifiers. They've got two or three very fine players but it's their commitment and teamwork that stand out. They fight right to the end, as they showed against Russia and Brazil. I'll be happy with the narrowest of wins - Diego, Uruguay keeper.
