With striker Didier Drogba's exit confirmed, the European champions look set to release both Kalou and Bosingwa.

Kalou, who joined the club in 2006 and has scored 60 goals in 254 appearances, and Portuguese defender Bosingwa are unlikely to be offered new deals.

The English Premier League giants are chasing several signatures.

Sao Paulo say they have rejected a bid of 32 million pounds for highly-rated 19-year-old Brazilian Lucas Mauro.

Chelsea are also after the signature of Belgian Eden Hazard, but the Lille attacker has plenty of options with both Manchester United and rivals City interested.
