Celtic were swept aside by a rampant Paris St-Germain, who hit seven in the Champions League at Parc de Princes during Wednesday's clash.
Brendan Rodgers' side opened the scoring in the first minute through Moussa Dembele, but were then swamped.
Neymar scored twice, then created the third for Edinson Cavani, before Kylian Mbappe struck before half-time, the BBC reports.
Marco Verratti, Cavani, and Dani Alves scored in a five-minute second-half blitz as Rodgers' Celtic side conceded seven goals for the second time.
The victory was PSG's biggest win in the Champions League, and a chastening night for the visitors, who lost 5-0 to the French side at home earlier in the group.
However the Scottish champions still have the advantage in the fight to finish third in Group B and qualify for the Europa League after bottom-placed Anderlecht lost their fifth game in a row, this time 2-1 to Bayern Munich.
PSG have scored 24 goals in their five matches - a Champions League group stage record, with one game still to play.
