If Neymar is unable to play in the first match, I think Barcelona will win the match. Barcelona now has a great forward lineup. Almost everyone is in form. Their only weakness was their defense. Koeman will take advantage of this opportunity if Neymar is injured. He may use a new tactic to keep Mbappe from scoring
Neymar would miss the tie against Barcelona next week; and also there is nothing great about the Barcelona forward line because they are only good on paper. They could not score a goal away at Sevilla last night; and Koeman is tactically inept and having a bad defensive line and structure. It remains to be seen how The tie would go; but i am tipping PSG for victory
