This will be a tough game, PSG have quality players and they will want to perform as CL is their window on the world to look at them, I think they will underestimate us, as Neymar's comments already show, we need to be at a high tempo and get stuck into them, not let the settle, the front 3 will need to put in a performance.
I can't see Klopp making too many changes, as a good start to CL is important.
