Having already been linked with Arsenal prior to the Christmas period, it seems that the prolific Brazilian striker Diego Costa is attracting much attention ahead of the re-opening of the transfer window tomorrow.
Having already been linked with a move to the Emirates Stadium, Costa now sees himself also linked to moves elsewhere, with Borussia Dortmund also rumoured to be interested in his services as they prepare for life without Robert Lewandoski.
Lewandoski seems all but set to join rivals Bayern Munich and follow the path of Mario Gotze in making the controversial switch to the Allianz Arena.
But Chelsea are also linked with a move for Costa, as Mouriniho continues to see his strikers struggle for goals; a struggle that has seen the Chelsea boss already concede defeat in the title race, as his faith in Torres and Eto'o has not been repaid in the manner the 'Special One' would have expected.
And given the release clause in Costa's contract, free spending Chelsea would have no problems in financing any move for the La Liga star.
But could they kill two birds with one stone with a move for Costa? Having splashed a massive £50 million on Torres, the former Atleti and Liverpool striker has shown mere glimpses of the impressive form that saw him make his way to the Bridge.
Mourinho has given the Spaniard his chances this season as manager's before him did, but he does not look like the Torres that was feared in a Liverpool jersey.
Having been a fan favourite at Madrid during his early years, could Chelsea possibly offer Madrid a swap deal that would see Torres return to his native Spain?
Given the individual form of each player, it seems a crazy suggestion, as Costa is one of the most prolific strikers in Europe at the moment. But given his history at the club, a deal for Costa could well include Torres, as this would shift a weight off Chelsea. Is it a viable option that Chelsea should consider?
With Dortmund surely being able to guarantee Costa a starting place should Lewandoski leave the club, Chelsea will need to act quickly if they do have an interest in the hot shot. And a possible deal including a return to the Spanish capital for Torres could put them in a better position, with Madrid talking strongly about keeping hold of another shining star.
