Liverpool striker Fernando Torres has suggested that Ronaldo "carries United on his back in some matches".
With no hint of irony from the man who has scored 22 of Liverpool's 60 Premier League goals this season, Torres has hinted that United are a one-man team.
He suggests that to beat Sir Alex Ferguson's team in the Champions League semi-finals, Barcelona need only to nullify the Portuguese attacker.
"I watch Ronaldo every weekend and he is massively impressive," said Torres.
"He carries United on his back in some matches.
"Barca have no idea how spectacular Ronaldo is or how far ahead of every other player in the world he is right now.
"But if they keep the ball away from him Barca will get to the Champions League final.
"United suffer against teams who keep possession of the ball."
