Cole Palmer scored two goals and made another as Chelsea stunned Paris Saint-Germain in the final of the Club World Cup on Sunday, beating the European champions 3-0 at the MetLife Stadium to win the first edition of Fifa's new competition.
PSG were the favourites for a game attended by Donald Trump after coming to the United States fresh from winning the UEFA Champions League and having destroyed Real Madrid 4-0 in the semi-finals.
But having been three goals ahead midway through the first half in the semis, this time the roles were reversed as PSG found themselves 3-0 down by the break.
Chelsea's Cole Palmer scores against PSG.
Palmer opened the scoring midway through the first half and struck again to make it two on the half-hour mark, before taking advantage of passive defending to set up Joao Pedro for the third on 43 minutes.
A bad day for PSG was summed up when Joao Neves was shown red following a VAR review four minutes from the end for pulling Marc Cucurella by the hair off the ball.
It was a scoreline that few could have predicted as Chelsea capped what has been a long but memorable season — they are the first ever winners of the 32-team Club World Cup having also won the Uefa Conference League and finished fourth in the Premier League.
They will also take away around $125 million in prize money, meaning the prospect of a drastically curtailed summer break before returning for next season will surely feel worth it.
For PSG, meanwhile, the financial rewards are similar but there will be genuine disappointment at falling short of adding this title to their Champions League triumph and French league and cup double.
Nevertheless, conquering Europe was always the main aim this season for Luis Enrique's team, who now have exactly a month to digest this and take a holiday before returning to action in the Uefa Super Cup against Tottenham Hotspur.
Trump in attendanceThere was a real sense of occasion at the MetLife Stadium, with the backdrop of the Manhattan skyline and with President Trump in attendance along with First Lady Melania Trump in a crowd of 81,118.

There was even the first-ever half-time show at a FIFA tournament, adding a Super Bowl feel to a final played at the home of NFL sides the New York Giants and New York Jets.
As for the football, for the second time in six weeks PSG found themselves involved in a final that quickly turned into a one-sided affair.
The club claimed a historic 5-0 win over Inter Milan in the Champions League final, but here they were ripped apart by Chelsea on another hot afternoon.
Palmer almost put Chelsea ahead inside the opening 10 minutes, before PSG should have scored at the other end only for Desire Doue to try to pass to Achraf Hakimi rather than shoot inside the box, allowing Cucurella to block.
It was Chelsea who struck in the 22nd minute as Malo Gusto got the better of Nuno Mendes down the right before seeing his shot blocked by Lucas Beraldo. The ball came back to Gusto and he teed up Palmer to finish into the bottom-left corner.
Palmer has been the face of Chelsea on billboards in the United States during the tournament and he lived up to his star billing by scoring again on the half-hour.
Released on the right with PSG left-back Mendes out of position, Palmer advanced towards the box before stroking a low shot into the same corner.

Joao Pedro played a part in the build-up to that goal and the Brazilian, signed during the tournament from Brighton, then got his name on the scoresheet to make it 3-0.
Scorer of both goals against Fluminense in the semifinals, he clipped a shot past Gianluigi Donnarumma after being supplied by Palmer.
PSG had conceded a single goal in their previous eight matches and they never really looked like producing a comeback, even if Neves headed just wide in first-half stoppage time.
Substitute Liam Delap almost got a fourth for Chelsea midway through the second half, before Neves was shown red to complete a bad day for PSG.
