The German veteran even contrasted Leo's record against Bayern Munich with that of bitter rival Cristiano Ronaldo.

Wednesday was another embarrassing day for PSG as the French giants crashed out of the UEFA Champions League on a whimper yet again, with Bayern Munich star Thomas Muller deciding to troll Lionel Messi following another frustrating European display from the Argentine.

The Ligue 1 leaders faced the reigning Bundesliga champions at the Allianz Arena for the 2nd leg of their round of 16 match-up, having lost the first tie 1-0 at the Parc des Princes.

The return leg didn't fare differently as Galtier's men fell to a 2-0 loss, thus crashing out via a 3-0 aggregate scoreline.

Messi, who struggled in both legs, was one of several players to be criticized after his lackluster performance against the Bavarians. The seven-time Ballon d'Or winner, who recently inspired Argentina to the 2022 FIFA World Cup, was unable to produce moments of magic for Les Parisiens when in need of a comeback.

And to make things worse, Muller, a player who has gone viral several times before due to how outspoken and frank he is, added insult to injury when talking about La Pulga in his post-match interview.

The 33-year-old, who was in a gleeful mood after being named Man of the Match, reminded everyone of Bayern Munich's brilliant record against Messi in this competition. Additionally, Muller contrasted this with how his team has fared against Cristiano Ronaldo, which might be seen as a hint at where his thoughts lie in the GOAT debate.

"Against Messi, things always go well at all levels in terms of results," Muller said, as per the Daily Mail.

"At club level, Cristiano Ronaldo was our problem when he was at Real Madrid. 

"But I have the greatest respect for Messi's World Cup performance. 

"Messi's individual performance at the World Cup was amazing. He carried the whole squad. 

"It's not so easy to play at a team like PSG. It's difficult to get a really good team balance."

This is the second year running in which PSG crashed out of the UEFA Champions League in the round of 16, which coincides with Messi's arrival in the French capital. Prior to that, Les Parisiens reached the final and semifinal stage in back-to-back seasons.

However, the biggest concern surrounds the club and how much they have lavishly spent on this unsuccessful project. Additionally, the future of Messi, Neymar, and Mbappe remains unknown, thus painting a bleak picture of what's to come.
