Chelsea are the odds-on favourites to sign Atletico Madrid striker Diego Costa.
The Blues have been linked with a move for the 25-year-old Spanish international for a considerable amount of time but have so far failed to entice Atletico Madrid into selling their prized asset.
Chelsea's failure to capture Costa could change this summer however as Blues boss Jose Mourinho is stepping up his efforts to land the highly-rated forward.
Costa proved to be a menace for Chelsea on Wednesday night as the striker scored a crucial goal to knock Mourinho's side out of the Champions League.
His goal will make Chelsea's manager and owner even more desperate to get their number one striker target.
Mourinho's three options in attack - Fernando Torres, Samuel Eto'o and Demba Ba - have all failed to perform on a regular basis and could therefore be sold at the end of the season.
Sky Bet's decision to shorten Costa's odds on joining Chelsea shows they are in pole position to land the £30million-rated goalscorer.
SkyBet odds on Diego Costa's next club:
Chelsea - 1/3
PSG - 14/1
Arsenal - 18/1
Manchester City - 18/1
Barcelona - 20/1
