Messi won a record sixth Ballon d’Or award on Monday at a colourful ceremony held in Paris.
Virgil van Dijk and Cristiano Ronaldo came in second and third-place respectively, with Mane occupying fourth.
However, many football fans believe Mane deserved the award after enjoying a fruitful year with both club and country.
Speaking on Mane’s position, Messi said it’s a shame that the Senegal international didn’t come closer to the award.
The Barca star revealed that he voted for Mane, while praising the 27-year-old’s exceptionality on the pitch.
“It’s a shame to see Mane finish in fourth place,” Messi said in an interview with Canal+.
“But I think there have been a lot of great players this year. That’s why it was difficult to choose a particular player. But I chose Sadio Mane because he’s a player that I like.
“Mane achieved a great year that was exceptional for the entire Liverpool team. That’s why I chose him. I repeat, there were a lot of very great players this year, so the choice was difficult.”
