The 21-year-old Messi scored several breathtaking goals for Barca last season, and also helped Argentina defeat Nigeria 1-0 to win the Olympic gold medal at Beijing in August.
Messi has stepped up his form since then, with nine league goals in 11 games for Barca -- one less than he got in 27 games last season -- as he continues to develop a flourishing partnership with Cameroon striker Samuel Eto'o.
"He is the kind of player I really like," Kaka said.
"Like Cristiano Ronaldo, he dribbles, he scores. Messi often does it all on his own."
Torres helped Spain win the European Championship in June, scoring the lone goal in the final against Germany.
