How much a team worths doesn't define how good they are. City is worth 1+ billion but they are out. To be fair they did played against Real Madrid, another 1+ billion team, so I can't blame them for it, but look at the league and see how terrible Manchester City is doing at the league this moment. That should tell you all you need to know about the worth of a team. Or look at United, they are worth greatly and they are not even in the top 12 right now at premier league as well.
So, this valuation comparison means nothing, while it also shows the truth at this moment because PSG is much better team. Sure Villa could beat any other French team, but when it comes to PSG, they are just too strong to be beaten by Villa and what they have.
