#1 Lionel Messi (Barcelona)

This man has made a career out of delivering fantastic moments on the pitch and producing for his side when needed the most.
Messi is a favorite to win the Ballon d'Or this year and would do everything in his power to stop Chelsea in a glamour round of 16 tie.
Barcelona has been on a roll this season and, their performances could definitely see them take the Champions League home.
Messi is the most dangerous player in the game and now has a veteran's approach to these competitive games.
Considering that Chelsea has not been brilliant this season, a guy like Messi could take advantage of any errors and punish them as he has failed to do in previous encounters.
Expect the magician to produce another sensational performance and possibly go all the way to the final of the UEFA Champions League.
