Juliano Belletti admits he left Chelsea too soon.
The Brazilian enjoyed three years at Chelsea and rates his time in the Premier League the best of his career.
Belletti left Chelsea for Fluminense and said: "I spent three years at Chelsea (2007 to 2010). It is the best competition there is to play. The structure of the clubs, the stadiums, the level of the teams, the behavior of the crowd.
"At this point, I regret having left, but remembering the tendon pain I realize I could not go on."
