The former Newcastle striker has not been included in Chelsea's match day squad for their last two outings and has slipped down the pecking order following Samuel Eto'o's arrival
Arsenal have made an enquiry to sign Demba Ba on loan from Chelsea, Goal can reveal.
The Gunners have been in contact with the Blues about taking the Senegal striker for the rest of the season.

The forward has not even made the bench for Chelsea's last two fixtures despite being fully fit, and slipped even further down the pecking order when the Blues signed Samuel Eto'o last week.
With Fernando Torres and Romelu Lukaku also at Stamford Bridge, Ba is unlikely to feature much this season.
Chelsea can trim their wage bill by loaning out the forward but might prefer him to go overseas rather than to a direct Premier League rival.
Arsenal had an interest in signing Ba permanently in January when he was at Newcastle United but were concerned about his history of knee trouble.
