Paris Saint-Germain are reportedly ready to bid for the Blues goalkeeper.
But it is the former that hold the greater advantage in their pursuit of the 32-year-old - because of Edinson Cavani.
The Standard claim Jose Mourinho is an admirer of the Uruguayan, who joined PSG for a fee of £55 million, and the Ligue 1 side could use Cavani as bait to lure Cech to the Parc des Princes.
Due to the 27-year-old's probable price tag, Cech would likely be used to bring the fee down for Cavani, with the Blues still sending money in the other direction to offload the goalkeeper.
The Czech shot stopper has been at Stamford Bridge since 2004 but all the indications are that the return of Thibaut Courtois will end his reign as Chelsea no.1.
Cech himself is believed to prefer a move away rather than a place on the bench.
Whether a swap deal for Cavani would be worth it for the Blues is another matter, however, as questions have been asked of Cavani's ability in big games, while Mourinho's side already have an abundance of talent going forward.
The Chelsea boss has also previously stated that both Cech and Courtois will be allowed a fair shot at claiming the no.1 spot.
The 32-year-old, then, could end up staying in west London, while at the same time saving the Blues the millions they would have spent on PSG man Cavani. Laurent Blanc's side, though, may have other ideas.
Would a Cavani/Cech swap deal be worth it for Chelsea?
