Having failed to impress since his world-record transfer in 2018, Arrizabalaga may leave Stamford Bridge during the summer transfer window.
However, finding a club interested in paying the £72m which Chelsea paid for the Spaniard will prove difficult, seemingly resulting in the Blues being keen on a part-exchange deal.
According to El Chiringuito, the Premier League giants are prepared to part with £25m plus Arrizabalaga in order to secure an agreement for Oblak.
Although Oblak has over three years left on his contract, Atletico may be open to selling the Slovenia international for the right price.
That said, the La Liga outfit will likely demand a bigger fee from Chelsea, aware that Arrizabalaga's stock has dropped in recent months. body check tags ::
