The styles of both Jose Mourinho's men and the Blues have attracted criticism in the past for being too defensive.
And perhaps with that in mind, Messi told the Times magazine
"Football is a game. I'm trying to have fun on the pitch, always, just to play.
"That's why I do it. The day I stop having fun is the day I retire...I never want to lose that spark, that passion.
"Today, teams are playing more statically, more for the final score than producing good football.
"For them, it's more important to win than to play well. We need more players with passion coming up for the good of football."
