Chelsea aren't bad at all, but they need to at least be just as good as PSG, clearly they're not, but as it's been pointed, we have seen crazier things happen in spot, I don't think anyone would have even tipped Chelsea to come this far, although they've had their own fair share of luck when it comes to who they were paired with at different stages enroute to the final. This probably going to be the only game they'd have to play pretty well in order to win.
