Chelsea could be set to use Deco and Ricardo Carvalho as bait to sign Atletico Madrid striker Sergio Aguero in the summer.
Portugal international Deco, who still has another year remaining on his Blues contract, recently confirmed his desire to quit Stamford Bridge after struggling for first team action under Carlo Ancelotti.
And, while he is looking for a return to Brazil to be nearer his family, it is being reported that Chelsea will try and persuade him to move to Spain with Atletico on a free transfer in an effort to get the Primera Liga outfit to part with their £35million star man Aguero.
Meanwhile Portuguese defender Carvalho could also be thrown into the deal if Atletico agree to a player-plus-cash deal for the Argentinian, who has already scored 15 goals in all competitions this current season.
