Xelaju have their captain and key midfielder suspended and will not play in their own stadium, but on the national stadium with artificial turf. They'll not match the Mexican team in skill, but will try to play with passion. Still, there is no real home factor so it will not be the same. I do not see Xelaju having depth to replace their captain, who is the heartbeat of their team.
Monterrey have left some key players in Mexico, but will still arrive with impressive depth, with Anthony Martial and Oliver Torres having big roles. The artificial turf can be tricky, and to be honest Monterrey would not panic if they don't win, and this is the risk. It is common for Mexican teams to show up with a flat attitude in the early rounds because they know that they will win at home. However they show fine goal scoring form right now, making me want to take a chance on them to get past a decimated Xelaju side. Small stakes, relying on the squad depth to be decisive.
