Newcastle had been the favourites to sign the Senegal frontman but their odds have drifted out to 12/1 with punters now seeing the Gunners as the most likely suitors.
Sky Bet Football Trader Chris Spicer said: "Ba looks surplus to requirements at Stamford Bridge but whether the Blues are willing to allowing him join a rival club remains to be seen.
"With Mesut Ozil also extremely short odds to join, the Gunners look set to finally bring in the neccessary reinforcements, but we're still refraining from cutting their title or top-four odds."
