There are several scenarios that could happen in this Group C match. even Saudi Arabia has the chance to subvert Mexico, if luck is on their side. in fact Saudi Arabia gave us a surprise, in the first game against Argentina. Likewise with Argentina, on paper Messi and his friends will easily qualify in the group phase. but in fact, they lost points in their first game.
Personally, Argentina is our favorite team. however, it seems that we do not expect more Argentina to be able to advance to the final round. Poland isn't a very strong team, but they won't be easy to beat either. the reason is, Lewandowski and his friends have packed 4 points, Poland only needs a draw and hopes that Saudi Arabia will overthrow Mexico. there are various scenarios that can occur, all teams in this group still have hope.
however, I am quite optimistic that Argentina will win the match. for Saudi Arabia vs Mexico, it looks like this fight will end with a thin score.
