The Round of 64 tie in Castres was never in doubt from the moment Mbappe opened the scoring in the 17th minute, yet the France striker was wasteful despite boosting his goal tally for the season to 25 in all competitions.

Marco Asensio starred for PSG, orchestrating the downfall of opponents operating in the sixth tier of French football, and the Spain star was on target himself shortly before half-time.

Mbappe was the only player to keep his place in a side showing 10 changes after last week's 2-0 Champions Trophy victory over Toulouse, but Goncalo Ramos was first to test the impressive Revel goalkeeper Cyril Garcia, who saved a shot bound for the top-left corner.

Mbappe and Asensio went close as early pressure built on the underdogs’ defence and in the 17th minute it cracked, Carlos Soler finding Mbappe, who fired home.

PSG was dominating possession against outclassed opponents with Asensio, Mbappe and Nordi Mukiele all going close.

Ramos teed up Mbappe and his first-time shot flew high over the crossbar but the search for a second goal ended in the 39th minute when Maxence N’Guessan poked a cross into his own net.

Revel’s resistance was melting away and they were undone two more times before the interval with the influential Asensio the next on target before Mbappe nodded in his second.

The second half was only three minutes old when Mbappe made it 5-0, Revel’s over-stretched defence offering Asensio the chance to score, only for the Spain star to provide his team-mate with an open goal.

Garcia was being kept busy in the home goal as PSG continued to press but he was at fault for a penalty conceded in the 72nd minute when he took out Ramos, who converted from the spot.

Randal Kolo Muani added the seventh from close range and Cher Mdour produced a stylish finish having been set up by Mbappe, before Muani completed the scoring on the stroke of full-time.
