PSG's pressure soon paid off but Neymar's opener wasn't without controversy.

Celtic felt they should have had a free-kick in the PSG half after Scott Sinclair went down but the visitors took full advantage as Adrian Rabiot's quickly-played ball behind Anthony Ralston found the Brazilian who expertly lifted a shot over Craig Gordon.


Emery had identified Leigh Griffiths as the danger man for Celtic before the game and the striker came close to an equaliser when his curling free-kick was tipped over by Alphonse Areola.

Mbappe then showed why PSG are prepared to make him the world's second-most expensive player when he grabbed his second goal in two games since joining on a season-long loan from Monaco.

Neymar's headed ball across goal was missed by Cavani but the 18-year-old, who PSG have an option to buy for a fee that could reach 180 million euros, pounced to fire home.

A moment of madness from Celtic allowed the French side to add to their advantage before the break as Jozo Simunovic needlessly pulled back Cavani in the box.

The Uruguayan took the spot-kick himself and sent Gordon the wrong way.

Celtic improved after the break as PSG took their foot off the gas but two late goals left the Scottish giants with their biggest ever home loss in Europe.

Lustig scored an own goal after substitute Julian Draxler drilled the ball across goal before Cavani rose at the back post to send a sublime angled header past Gordon from Layvin Kurzawa's cross.

"Defensively we were just too far off them and secondly I was disappointed in how we retained the ball. We didn't keep the ball for long enough," Celtic manager Brendan Rodgers said.

"If you do that against what is arguably the best team in the world just now they will punish you."
