Monaco cantered to a galling 3-0 defeat of league-leading Paris Saint-Germain in Ligue 1 on Sunday afternoon.
PSG's Champions League capitulation has been painstakingly dissected but Monaco came into the contest after a European elimination of their own.
Yet, the hosts rebounded from their Europa League exit on Thursday with a proactive start, pressing PSG's laboured attempts at playing out from the back. Wissam Ben Yedder picked Leandro Paredes' pocket on the edge of PSG's penalty area ten minutes in but Jean Lucas took the ball off his top-scoring skipper, blazing his attempt at a gaping goal high and wide.
Ben Yedder back-heeled Monaco into a thoroughly deserved lead in the 25th minute, sumptuously converting Youssouf Fofana's cross after both scorer and provider burst beyond soporifically stationary blue shirts.
The closest PSG came to landing an equaliser in the opening 45 minutes was via the lackadaisical touch from Monaco keeper Alexander Nubel, almost controlling a back pass into his own net.
Mauricio Pochettino reverted to a back-three during the interval. Yet, aside from sporadic bursts by Kylian Mbappe, PSG failed to maintain any consistent threat.
Despite the presence of three designated centre-backs, Monaco's substitute Kevin Volland still managed to find space in PSG's box to double his side's lead in the 68th minute.
Ben Yedder punished PSG's dawdling to compound the league leaders' misery in the final ten minutes. Catching Marco Verratti in possession on this occasion, the Monaco captain slid Volland into the box, luring Presnel Kimpembe into a fittingly rash penalty concession which Ben Yedder himself converted.
PSG's heaviest defeat since April 2019 was their fourth consecutive loss on the road following an afternoon to quickly forget.
Paris Saint-Germain player ratings vs Monaco
1. Goalkeeper & defenders
Gianluigi Donnarumma (GK) - 5/10 - Kept the score down with a raft of sharp stops and proactively darted off his line but punched Ben Yedder's penalty into his own net.
Achraf Hakimi (RB) - 5/10 - Repeatedly frustrated when involved in the build-up of moves, but found himself at the sharp end of more than one attack, forcing a couple of good saves from Nubel.
Marquinhos (CB) - 2/10 - Groggily trudging through treacle throughout.
Presnel Kimpembe (CB) - 3/10 - Emblematic of the insipid start PSG endured when caught dozing in the sun for Ben Yedder's opener.
Nuno Mendes (LB) - 5/10 - Alert when forced into defending the low crosses which were fizzed into his six-yard box with startling regularity.
Danilo Pereira (CM) - 4/10 - Ambled on the periphery of midfield before he was installed as the anchor of the second half back-three.
Leandro Paredes (CM) - 3/10 - Painfully pedestrian in possession, very fortunate that Jean Lucas didn't directly ensure he gave away the opener.
Marco Verratti (CM) - 4/10 - Nothing was coming off for the vocal Italian; handballing attempts to control simple passes and tackling the ball into the path of opponents.
Georginio Wijnaldum (RW) - 4/10 - Caught between midfield and the front line, Wijnaldum failed to make an impact in either area.
Kylian Mbappe (ST) - 6/10 - A rare source of urgency amid the dozing dross PSG served up for much of the match.
Neymar (LW) - 3/10 - More distracted by getting the last word in a petty, ongoing scrap with Monaco's right-back Ruben Aguilar than getting past him with the ball. Departed the pitch to a volley of whistles and boos.
Mauro Icardi (ST) - 5/10 - Had an unconfident left foot swipe saved by Nubel following a quick free-kick.
Idrissa Gana Gueye (CM) - N/A
Julian Draxler (LW) - 5/10
Abdou Diallo (LWB) - 5/10
