It just had to be him.
Heading into Tuesday's meeting between PSG and Real Madrid, there was one narrative to rule them all: the future of Kylian Mbappe, who is expected to leave the former for the latter in what would be the biggest free transfer of all time.
There was only going to be one player to make the difference, and Mbappe didn't let us down.
Mbappe had the first half's only shot on target, with Real more than happy to sit back and play for the 0-0 draw as soon as the referee's whistle blew.
In fact, Real's first shot came with the final kick of the ball in the first 45. Casemiro's weak header trickled wide, and that was a close as Real came as they didn't even manage a shot on target during the whole game.
That's the first time in at least the last six seasons that Real have not had a single shot on target in a Champions League game - that run likely stretches even longer but records haven't been keeping count.
It looked like we'd get a breakthrough from PSG midway through the second half when Mbappe (who else?) won his side a penalty.
Dani Carvajal couldn't keep up with Mbappe all night long and eventually let the pressure get the best of him as he lunged in in the box and left the referee with no choice but to point at the spot.
Up stepped Lionel Messi...and he missed.
With nobody else prepared to make the difference, the job was left to Mbappe.
With just seconds left on the clock, the 23-year-old took the game by the scruff of the neck and slotted the ball through the legs of the otherwise-excellent Thibaut Courtois to seal a well deserved victory for the Parisians.
As you'd expect, Twitter was loving it.
