Chelsea must play the bus and wait for a penalty shootout

It seems the weather will not be on their side (hotter weather would probably be to their advantage), but the rain will probably also help them defend.
PSG looks like a team without weaknesses, but who knows, maybe on Sunday there will be the same game as with Liverpool in Paris, when PSG should have won 3-0 but lost 0-1.
This PSG team isn't the type of team Chelsea should play the bus and wait for a penalty shootout because the PSG team knows how to break and penetrate their opponents defense, and if Chelsea adopts that strategy, PSG will beat Chelsea easily. Attack is the best form of defense, so I expect Chelsea to play attacking football against PSG so that all the pressure will not be on them.
