Paris Saint-Germain steamrolled Lionel Messi's Inter Miami 4-0 on Sunday to reach the Club World Cup quarterfinals, where it will face Bayern Munich, which overcame a spirited challenge from Flamengo.

Bayern defeated the Brazilians 4-2 in Sunday's other last 16 clash behind a brace from Harry Kane.

Miami hoped Messi's magic could help it produce an unlikely result against the Argentine star's former club, but the Major League Soccer side was dismantled by Luis Enrique's team.

Messi and his former Barcelona teammates Luis Suarez, Sergio Busquets and Jordi Alba did well to reach the last 16, but the gulf in quality between the teams was laid bare in Atlanta.

Joao Neves netted twice for PSG, which benefited from a Tomas Aviles own goal, while Achraf Hakimi was also on target for the French treble-winner.

"Clearly, we are experiencing a historic season for our club, we aim to go far in this competition," Luis Enrique said.

Messi was the main draw, as fans chanted his name, and most of the 66,000 in the crowd were clad in Miami's hot pink, interspersed with Argentina shirts.

PSG dominated from the start and took the lead when Neves nodded in unmarked at the back post from a free kick.

With the Ligue 1 champion pressing high and keeping possession, Javier Mascherano's Miami found it hard to get Messi involved. The 38-year-old's intermittent interventions were not enough to hold back the Parisian tide.

PSG doubled its lead in the 39th minute when veteran holding midfielder Busquets got his footwork wrong, with Ruiz stealing the ball and combining with Bradley Barcola to set up Neves again.

"He played a very good game ... in this team everyone can score and make decisive contributions," Osumane Dembele said.

Aviles then deflected Desire Doue's cross into his own net, and Hakimi netted the fourth before halftime to put PSG out of sight.

Messi, an eight-time Ballon d'Or winner, produced a brilliant pass for Suarez early in the second half, but the Uruguayan could not finish to offer Miami a lifeline.

Despite the impossibility of a comeback Messi seemed determined to bow out with a bang.

When Suarez was fouled on the edge of the box, Messi had the chance to repeat his free kick winner against Porto in the group stage, but his effort hit the wall.

Luis Enrique sent on winger Dembele for his first appearance at the tournament after a hamstring injury, but the Frenchman looked rusty, and PSG could not extend its advantage.

Miami's second-half performance was respectable, and the defeat was by a lesser margin than the French side's 5-0 thrashing of Inter Milan in the Champions League final.

"I think we were above the expectations people had for us (at the tournament) ... obviously we were facing the best team in the world playing football right now, so it was difficult," Alba said.

Kane produced two lethal finishes as Bayern beat out Filipe Luis' Flamengo side, which was backed by a passionate following at Hard Rock Stadium in Miami.

"It's going to be another tough game — PSG have had an amazing season," Kane said.

"We played them earlier in the year, and we came out on top.

"We know it's going to be difficult, but we can beat anyone when we're at our level, we've shown that in the tournament so far."

Erick Pulgar headed Joshua Kimmich's corner into his own net, and Kane's deflected drive flew into the bottom corner as Bayern took a two-goal lead.

The three-time Copa Libertadores champion battled back as Gerson smashed a shot past Manuel Neuer to delight most of the crowd of 61,000.

Leon Goretzka restored Bayern's lead, but former Chelsea midfielder Jorginho reeled in the German club once more from the penalty spot.

Kane settled the contest with a fine touch and finish to set up the quarterfinal clash against PSG.

"We have to rest now, recover from this game, use every single day we've got to rebuild our energy," Bayern coach Vincent Kompany said.

"Then what more do you want? Top top sides playing each other on the biggest stage — we'll be ready for that."
