Chelsea are reportedly considering whether to launch an approach to sign Atletico Madrid goalkeeper Jan Oblak.
While a bid for Ajax's Andre Onana is a possibility, The Mirror suggests that Chelsea may look to bring in Oblak as Arrizabalaga's replacement.
Aware that the Slovenia international possesses a release clause well in excess of £100m, the Premier League outfit are keen to include Arrizabalaga in a part-exchange deal.
Nevertheless, despite potentially being able to reduce Oblak's valuation during negotiations, Chelsea may still need to part with at least £70m to get a deal over the line.
Oblak still has three years remaining on his contract at Wanda Metropolitano.
