Chelsea are preparing for a sudden flurry of offers for Petr Cech amid fears he is losing his duel with Thibaut Courtois to be first-choice goalkeeper.

Jose Mourinho has insisted he will not reveal before Sunday who will start their opening game at Burnley on Monday night.

Neither has been given any indication but Courtois appears confident of getting the nod after playing for 90 minutes in a friendly against Real Sociedad on Tuesday.

Cech, the No.1 since he arrived from Rennes a decade ago, seems less certain and will have to consider his future if Mourinho opts for the young Belgian. Both have two years left on their contracts.

Paris Saint-Germain and Monaco are keen to lure Cech back to France. Real Madrid are also interested and all three are ready to step up their pursuit.
