The deal is subject to the player agreeing personal terms and passing a medical, the three-time Premier League champions said on their official website.

Chelsea were chasing Sevilla's right-back Daniel Alves but the Spanish club's financial demands were not accepted by Blues, who have turned their attentions to Belletti.

Chelsea boss Jose Mourinho is not convinced by the form of duo Paulo Ferreira and Glen Johnson and thus, looked for other alternatives at right-back.

The 31-year-old Belletti fell out of favor with Barcelona coach Frank Rijkaard after the arrival of Gianluca Zambrotta last summer.
