This group is all over the place. All 4 teams have 3 points. This game will be very difficult to win in my opinion.
Serbia have the upper hand though, with a +1 goal difference. All they need is a tie to make it to the 2nd round, so they'll be playing a little more defensively than Mexico, which needs a win to get to 2nd place, but a tie can still qualify them in 3rd place.
Mexico will come out fighting, and might just score a goal, but I think Serbia is more than capable of scoring as well,
My expectations here is draw.
