The Blues are in the market for a new goalkeeper to replace Kepa Arrizabalaga this summer after a number of poor performances from the Spaniard this season.
The 25-year-old, who arrived for a world record fee in 2018, has failed to impress under Frank Lampard and was dropped on few occasions throughout this season.
Reports suggest that Lampard is now on the lookout for a replacement for Kepa, with Oblak one of the names at the top of the list.
The Slovenian is set to hold talks with Atletico about his future after they were eliminated out of the Champions League this week.
The Spanish club has remained defiant in their stance over the Slovenian, with them insisting that he will only be sold should his £109 million release clause be met.
However, Atletico’s stance could be softened with the arrival of a potential replacement for the Slovenian keeper.
The 27-year-old who kept 17 clean sheets in La Liga this season signed a new contract with Atletico only last year and that deal still has three years left to run.
Ajax keeper Andre Onana and Nick Pope, as well as Dean Henderson, are other options thought to be on Chelsea’s radar.
