Celtic sustained their heaviest ever home European defeat as Neymar led the way for Paris St-Germain in the Champions League group stage opener.
The world’s most expensive player coolly finished and then had a hand in PSG’s second, which was finished emphatically by Kylian Mbappe.
Edinson Cavani converted a penalty for the visitors’ third before the break.
Mikael Lustig’s own goal was followed by Cavani’s second of the night, a superb diving header.
Celtic have hosted many of the great powerhouses of European football in Glasgow over the years, but even those with the longest memories would probably struggle to recall a side as devastating as PSG.
Their speed of thought, speed of movement, accuracy and imagination was extraordinary. Their confidence on the ball – even when playing intricate passes in their own penalty area to get out of trouble – was a joy.
Quality on this scale costs big-time, of course. The biggest compliment you can pay the visitors is that they looked every inch the half-billion-pound team they are.
