Their Spanish coach is the mastermind of this new PSG, built from the ashes of the superstar era which saw Lionel Messi, Kylian Mbappe and Neymar the centrepieces of a dysfunctional, ego-ridden outfit who never resembled a team.
Luis Enrique, who also won the Champions League with Barcelona in 2015, ordered his players to park egos at the door – or jettisoned those who would not.
In their place is the perfect combination of brilliant individual skill bolted on to a savage work ethic and defensive solidity that will make them a formidable hurdle for Arsenal to overcome.
And the leader is Marquinhos.
The Brazil centre-half arrived at PSG from Roma in 2013, surviving Luis Enrique’s cull of big names because the coach is wise enough to see a consummate professional and world-class defender when he sees one.
He has formed a superb partnership with the formidable Willian Pacho, who played a key role in keeping Kane under wraps until the England captain’s strike in the dying seconds.
Kvaratskhelia and Dembele combined for the game’s defining moment, while 20-year-old Desire Doue – the young face of the new PSG – tormented Vincent Kompany’s side, coming close on several occasions in the second half.
And yet the glue that held it all together was Marquinhos, still peerless at 31, and with the uncanny knack of being in the right place at the right time while exuding calm authority.
To complete the picture, PSG’s midfield of Vitinha, Fabian Ruiz and Joao Neves is the well-oiled engine room linking it all together.
Ruiz’s pass in the build-up to Dembele’s goal was a thing of beauty – but he then reverted to doing the defensive dirty work Luis Enrique demands and which his team seems only too happy to deliver.
