Paris Saint-Germain are set to make the first move for Petr Cech as they prepare to bid for the demoted Chelsea goalkeeper, Goal understands.
The veteran was a high-profile casualty of the Blues' intense competition for places after being overlooked in favour of Thibaut Courtois against Burnley on Monday night.
As revealed by Goal, Cech will be encouraged to find a new club in the final fortnight of the transfer window following a decade as Chelsea's undisputed No.1.
Real Madrid and Monaco are among the clubs closely monitoring the 32-year-old's situation but the first formal offer is expected to come from PSG following confirmation of his downgraded status.
Salvatore Sirigu has begun the season in goal for the Ligue 1 champions but Cech would be regarded as an upgrade on the 27-year-old Italy international.
Monaco recently signed Fulham's Maarten Stekelenburg on a season-long loan but have a concrete interest in Cech.
Real captured Costa Rica World Cup star Keylor Navas earlier this summer before offloading Diego Lopez to AC Milan and would need to move on Iker Casillas if they are to land the Chelsea man.
Mourinho claimed on Monday that he wants to keep Cech but the west Londoners are believed to be ready to cash in on the keeper, who has two years remaining on his current contract, if they receive an offer that matches their £10 million valuation. A loan away from Stamford Bridge with a recall option could be a solution to what is a tricky issue for the club and player.
Chelsea already have an experienced understudy in place should he leave. Mark Schwarzer, Cech's backup last season, signed a one-year extension in July.
Cech is unlikely to accept a season sat on the bench after Mourinho's team selection against Burnley confirmed that Courtois will be given the chance to establish himself as the club's new No.1.
As revealed by Goal on Tuesday, Courtois is now prepared to sign a new five-year-contract that triples his wages to £90,000-a-week. He had held back on putting pen to paper until he was confirmed as the starter in goal.
Cech has established himself as one of the world's outstanding keepers during his decade at Stamford Bridge.
Since joining Chelsea from Rennes for £7m in 2004, he has made 479 appearances for the club and won the Champions League, the Europa League, three Premier League titles, four FA Cups and three League Cups.
