Monday's Champions League draw has pitted Barcelona and Manchester City against each other, and that means Lionel Messi will take on his great friend Sergio Aguero.

The pair teamed up together during the summer to guide Argentina to the World Cup final, but they enjoy a keen rivalry off the pitch when it comes to the video game of FIFA.

Messi revealed as much in a playful Facebook message after the draw.

He posted a picture of the pair together with the message: "Looking forward to playing in the next round of the UEFA Champions League. It'll be really nice to face my friend Sergio Aguero as I always beat him at FIFA, but let's see what happens on the pitch."

Let's see indeed.
