I wouldn't so readily dismiss a 4-1 away win in the Nou Camp in a CL last 16 tie.Barcelona were dreadfully arrogant in how attacking they were and they rightfully got torn to shreds.
They were far better in the 2nd leg. In fact how much Barcelona improved over the games should be the biggest source if encouragement. PSG have oodles of quality but the 1st half last night was possibly their only chance to catch us out and we rode it out.
With players like Mbappe, Neymar and di Maria they can turn a tie on its head in 5 minutes. There's justifiable confidence and there is bravado.
