Group B is the first group to conclude at the 2017 Men's U-20 World Cup, largely because Group A has the home team - South Korea - in it, and so its kick-off times are optimized for a local audience.
As such, we'll know the fate of CONCACAF qualifier Mexico before we know anything about the Group A teams.
The Group B standings after two games:
|Position||Team||Played||Won||Drawn||Lost||Goals For||Goals Against||Goal Difference||Points|
This Mexico-Venezuela match is effectively a playoff for top spot in the group. If that's all that were at stake, it would not be insignificant.
The winner of Group B will play the third-placed team from either Group A, C, or D (depending on how qualification of third-placed teams shakes out - only four from the six groups will progress to the knockout rounds) in the round of 16. The runner-up from Group B plays the runner-up from Group F, which might be a tougher proposition - or at least a more interesting one, since it might be the USA.
But the uncertainty of the opponent is such that mostly this game is about Mexico making sure it gets through to the next round, one way or another. Venezuela has already qualified for the knockout rounds, and will win Group B unless it loses this game to El Tri.
For Mexico, a draw would be sufficient to clinch the runner-up spot and ease any anxiety about making the next round.
Four points should be enough to get Mexico into the knockout rounds, even as a third-placed qualifier. But it will sweat over results in other groups if its loses this game because it will almost certainly finish third if it does so, since Germany is expected to trounce Vanuatu and finish the group stage with four points and a substantial, positive goal difference.
A loss in this game for El Tri means anxiously hoping that something like four points and a 0 goal difference is enough to finish as a one of the top four third-placed teams in the group stage. Better not to lose at all, of course - and that will be Mexico's target.
