Video: Celtic 0 Paris St-Germain 5
Celtic were on the end of their heaviest-ever European home defeat at the hands of Paris St-Germain in their Champions League group opener.
Brazilian Neymar gave the visitors an early advantage with a sharp finish inside the area. He then set up another for teenager Kylian Mbappe when heading back Marco Verratti's cross.
Edinson Cavani also converted a penalty after being brought down by Jozo Simunovic prior to the break.
Home defender Mikael Lustig later deflected in Julian Draxler's driven cross, and Cavani soon dived in to head a fifth before the end.
