Fabian Ruiz scored twice as European champions Paris Saint-Germain turned on the style in their reunion with Kylian Mbappe on Wednesday, thrashing Real Madrid 4-0 in the semi-finals of the Club World Cup to set up a final showdown with Chelsea.
Ruiz and Ousmane Dembele scored inside the opening nine minutes to stun Real and silence the majority of the 77,542 crowd who were wearing white at the MetLife Stadium outside New York.
The Spanish midfielder added another before half-time and Goncalo Ramos got a late fourth as Luis Enrique's side moved one game away from glory at FIFA's new tournament.
Victory against Chelsea on Sunday would complete a campaign of unparalleled success for the Parisians, who won the French title and then the first UEFA Champions League in their history in May.
After blowing away Inter Milan 5-0, the biggest victory in European Cup final history, PSG began their Club World Cup bid by putting four past Atletico Madrid and the ease with which they disposed of Real here was striking.
PSG's fluidity contrasted starkly with Madrid, who are a work in progress under new coach Xabi Alonso. Meanwhile Mbappe struggled to make any impact on his first start at the tournament and in his first game against PSG since leaving the French club a year ago.
The France captain was hoping for a different outcome against the team for whom he scored a club record 256 goals, and the defeat is a real blow to Real as they hoped to win the first 32-team Club World Cup to add to their record tally of 15 European Cups.
But PSG have improved without Mbappe and are now such a well-oiled machine that they appear unstoppable -- it would be a big surprise if they failed to beat Chelsea.
Real goalkeeper Thibaut Courtois made two superb saves inside the opening five minutes, the first to tip away a Ruiz shot, and the second to deny Nuno Mendes from point-blank range.
Yet Courtois could not prevent Paris from scoring in the sixth minute, as Dembele pounced on slack defending by Raul Asencio. The Real 'keeper saved at the forward's feet but Ruiz converted the loose ball.
Three minutes later and the contest was effectively over when Antonio Rudiger failed to control a simple pass from Jude Bellingham, allowing Dembele to run through before finishing low into the corner.
It was turning into a humiliating afternoon for Real as PSG got their third midway through the first half.
PSG then got their fourth after 87 minutes when Ramos controlled a pass from fellow substitute Bradley Barcola, turned and fired in.
