The first games of the 2017-18 UEFA Champions League season left some interesting facts and performances by top-caliber teams.

A new UEFA Champions League season has begun, with many records to be set and others to be established.

Without further ado, let's have a look at those facts that became a trending topic on social media, adding to them those that will be remembered by fans for a very long time.

Messi ends hoodoo, gets closer to CR7

As expected, Barcelona's rematch against Juventus saw Lionel Messi make headlines, as he scored past Gianluigi Buffon for the first time. The player has now scored 99 European goals for Los Blaugranas, and needs four more in UEFA Champions League history to hit the 100-goal mark.

Cavani makes history at PSG

With a millionaire investment, Paris Saint Germain kicked off this UCL season with a bang, having their deadly Mbappé-Neymar-Cavani trio scoring four of the team's five goals vs Celtic (the other one was an own goal). Edinson Cavani's brace for Les Parisiens made him break a club record set by none other than Zlatan Ibrahimovic.

Marcus Rashford enters EVERY competition with a bang

If English fans thought we would forget about their rising star, they were wrong! Marcus Rashford sealed Manchester United's return to the UCL with the third goal of the evening, and once again, made his debut in a competition with the right foot.

He also joined an elite list as a Man United scorer.

Chelsea give Qarabag unmerciful welcome to UCL

Antonio Conte's men returned to the top club competition in Europe with a six-goal display, the first under coach Antonio Conte. A brace by Michy Batshuayi capped an amazing performance by the Blues, which also set a negative record for the team from Azerbaijan.
