Messi, 32, is tipped to win a record sixth Ballon d'Or in Paris on Monday after enjoying another stellar year.
"I don't follow these awards galas because they are too long. My vote, well, I guess, is the same as yours," he told a news conference.
"I would vote for the best, obviously. Every year you always vote depending on how the seasons have gone for the players.
"But if you have to give it to the best, let's just give it to Messi and the problem is solved."
Ahead of their trip to the Wanda Metropolitano, Barcelona are second in LaLiga, three points behind rivals Real Madrid.
