Lionel Messi Poses with Goats While Saying He's Not the G.O.A.T.

G.O.A.T. MEETS GOAT

This is interesting ... Lionel Messi posing with a live goat for a photo shoot -- while explaining that he doesn't consider himself the greatest soccer player alive.

"I don't consider myself the best," Messi tells Paper ... "I think I am just another player."

Yeah, right.

As Paper points out, Messi has one of the most impressive resumes in pro sports.

"He has helped his team, FC Barcelona, win 32 trophies -- including nine Spanish Liga titles and four in the Champions League. He led the Argentine national team to the gold medal at the 2008 Beijing Olympic Games and brought them victory at the FIFA Under-20 World Cup in 2005."

He's also got 5 Ballon d'Or awards, 5 Golden Shoes and holds the Guinness World Record for the most goals officially scored in a season (50 in the 2011-12 La Liga season).

But sure ... just a regular player.

"On the field, we are all the same when the game begins," Messi adds.

Messi also talked about everything from his upbringing in Argentina to his charity work with UNICEF in the full PAPER x Sports article.

No word on who had to clean up after the goats.
