Spot on.
Both teams played Saturday and have a cup semi final this weekend which there will be half an eye on too.
Villa are a good side at home but tend to be pretty poor away. Emery will undoubtedly be thinking a point is good for Villa with their remaining games and set them up on the counter. So ball retention the way PSG did in the home leg is more beneficial than dynamic younger players who might leave us stretched.
No point kicking off until after the game if the result and performance warrants it.
