Against Las Palmas will not be too difficult for Xavi troops if we compare their respective strengths, but Xavi also needs to save his players energy because in front of him there is an important match that must really be maximized. Against PSG you need to be at full strength and not with a broken line-up. PSG is very ambitious to quickly steal points and that requires Barcelona to be ready to match PSG playing rhythm in Leg 1. Barcelona who must come as the visiting team, is certainly not the favorite and that will make PSG even more confident. Even though PSG is the favorite, it still won't be easy if Barcelona back line and midfielders are able to block Mbappe movements.
