Chelsea are reportedly keen to lure Argentine international, Javier Pastore to Stanford Bridge, and are prepared to offer Diego Costa as part of the deal.
Chelsea boss, Antonio Conte holds a long-term interest in the hit man, and is prepared to follow up on that this summer by making a stunning move for the Argentine.
Chelsea tried to sign Pastore in the January transfer window, but were knocked back by PSG, they are now prepared to once again try and sign the player and Antonio Conte is willing to let top scorer Diego Costa, go the other way as part of the deal.
PSG hold an interest in the Spaniard and have been looking for an opportunity to swoop in on the player ever since he had a training ground burst up with Antonio Conte.
Costa himself has done nothing to play down the possibility of him joining the French champions, insisting he was open to a move to the club which he describe as a “respected” club.
Pastore has seen his career stalled since the sacking of French manager Laurent Blanc, the Argentine has played only 15 times in all competitions this season, with new coach Unai Emery preferring other players.
