KYLIAN MBAPPE toasted the perfect day by scoring a special hat-trick for Paris Saint-Germain as they thumped Metz 5-0.
The striker, 23, was presented to his adoring fans before kick-off against Metz at the Parc des Princes.
Earlier on he put pen to paper on a staggering new three-year contract worth a whopping £500million in total.
That includes a £250m signing-on fee bonus plus £1.6m per WEEK after tax.
So his treble as the champions celebrated their Ligue 1 title cost the club a cool £533,000 EACH.
The first, on 24 minutes, saw him race through on goal, cut inside the onrushing goalkeeper and slide the ball in between the covering defenders – as bitter LaLiga could only watch on in anger.
Mbappe completed his hat-trick five minutes into the second half and 77 minutes after his new contract was confirmed as he pounced on Boubakar Kouyate who dawdled on the ball on the edge of the area.
The striker picked his pocket, rounded Marc-Aurele Caillard, and stroked into the unguarded net to ensure May 21 would be truly unforgettable.
And Mbappe may well have had more but was denied by the Metz goalkeeper and then struck the base of the post while Kouyate picked up a second yellow.
Angel Di Maria is expected to leave PSG after seven years and bowed out in style by making it 5-0.
Mbappe teed up Lionel Messi whose volley ricocheted back off the post and a very emotional Di Maria collected and dribbled in before bursting into tears.
He was consoled by Neymar and later substituted off as his beloved wife Jorgelina Cardoso also let the waterworks flow
But while the vast majority of the Parc des Princes was in the mood to party, Metz knew they could be relegated if other results went against them.
And Saint-Etienne’s late equaliser saw them leapfrog Metz into 18th place and a relegation play-off spot as PSG’s final-day victims went down.
