3. Ronaldinho
Ronaldinho is one of the most loved players ever to play for Barcelona. He won hearts with his feet, and let them do all the talking. There was no limit to what he could with the ball. Defenders were basically afraid to attack the ball when it was at his feet, scared of being embarrassed by him.
The stats also prove his brilliance. He scored 70 goals in 145 appearances for Barcelona and 5 titles in as many seasons. His departure was abrupt, but no one at the club has criticised over it. It might even have been for the better, as his career went on a downward spiral after he left the Camp Nou.
