We're going to see a lot of action tomorrow. 18 games in one day and it's a final round of the league stage, so for many it will be all or nothing game.
A word of warning to all casual gamblers who don't tend to do much research before betting - make sure the team you're betting for has actually any reason to approach the game seriously. For example, Liverpool is said to give a chance to their second-suit players and will let the main squad have a rest:

This could be a great chance for PSV to earn 3 points to bump their position in the table, although they are almost guaranteed to end up in the play-offs despite the outcome.
The team that currently has a number of points 13, 14 and 15 still has the opportunity to shift the positions between one another. You are right that the last match must be considered properly not to get caught up with the odds offered. Not to mention the teams that now have 7 and 8 points like Manchester City who are eager to shift the team that collects 10 points like the points owned by PSG. It takes a comprehensive analysis of all aspects.
The highlighted PSV vs Liverpool match can be a match that will be trapped. One more in my opinion is the match between Stuttgart vs PSG.
