• PSG, Bayern Munich, Real Madrid, and Barcelona all lost in a huge weekend of upsets in European soccer.
• The last time all four teams lost on the same weekend was 18 years ago in April 2003.
• "I'm really disappointed," PSG manager Mauricio Pochettino said after his side's loss to Rennes.

Paris Saint Germain, Bayern Munich, Real Madrid, and FC Barcelona all lost in what was a huge weekend of upsets in European soccer.

All four clubs had been unbeaten in their respective leagues going into the weekend.

PSG was swept aside 2-0 by Stade Rennais in Ligue 1 as Lionel Messi tasted defeat for the first time since his summer move to the French capital.

Bayern lost its first Bundesliga home match in almost two years as it was beaten 2-1 by Eintracht Frankfurt, while Real Los 2-1 to Espanyol in La Liga, with goals from striker Raul de Tomas and Aleix Vidal earning the Catalan side an unlikely three points.

Barcelona - while not an upset - fell at the hands of reigning La Liga champion Atletico Madrid. Luis Suarez, who left the Camp Nou for Atletico in 2020, was on the score sheet in a comfortable 2-0 win for Diego Simeone's side.

PSG's defeat to Rennes was perhaps the weekend's most shocking upset.

Despite Messi, Neymar, and Kylian Mbappe all starting up-front together, Mauricio Pochettino's side failed to register a single shot on target in what was a toothless performance at the Roazhon Park.

Gaetan Laborde tucked home a superb cross from Kamaldeen Sulemana just before the break to give the hosts the lead.

Flavien Tait then added a second just moments after the players had returned to the pitch to complete the scoring.

Kylian Mbappe thought he had pulled a goal back for PSG midway through the second half, only for it to be disallowed for offside by the video assistant referee (VAR).

The French striker is now on a run of five matches without a goal, while Messi is yet to open his account for PSG in the French top flight.

"I'm really disappointed with everything," said Pochettino after the match. "I think now we need those two weeks but the players are going to be involved on international duty. It's time to think and to prepare the next run of six games in the upcoming months."
