PSG improved as the competition progressed.Aston Villa were the better team against them after the first 25 minutes at Villa Park. Second half, especially.
They were dire in their first five matches, the only win was a 1-0 against Girona.
Had we beaten them after being 2 nil up ( they scored their first goal in the 60 mins) they wouldn't even have qualified for the next stage if the competition.
They lost the first of their 3 CL matches against Arsenal badly where 2 nil was being favourable to them
Then then went on to beat Arsenal twice.
I'm not sure what changed but some of their football in the later stages was brilliant and exciting.
