Kepa Arrizabalaga's short Chelsea career has been on the decline for the better part of a year now.

Ever since the Spaniard openly challenged Maurizio Sarri's decision to substitute him in the 2019 League Cup final, the former Athletic Bilbao man's reputation and form have suffered.

Under Frank Lampard, Kepa has been ousted from the team on numerous occasions and since his reinstatement for the Premier League's restart, the 25-year-old has flattered to deceive.

He always looks prone to making a high-profile mistake and it's no surprise to learn that Lampard and the Chelsea hierarchy are actively looking to replace him this summer.

Ajax's Andre Onana has been a name heavily linked with a move to Stamford Bridge, but it seems the Blues have a new number one target.

Lampard with Chelsea

According to the Mirror, Chelsea are aiming high and are looking to strike a deal for Atletico Madrid's Jan Oblak - a man revered by many as the best 'keeper in the world.

The Slovenian's release clause at Atletico currently stands at £120m, but Lampard's side are looking to barter down that price by including Kepa in a player-plus-cash deal.

That's essentially the equivalent of swapping a quad bike for a brand new Lamborghini, isn't it?

Were Atletico to even consider selling their 27-year-old superstar, they would surely want a better 'keeper coming in to replace him.

GIVEMESPORT'S Danny Ryan says...

If Chelsea pull this deal off, it will be the steal of the century.

Not only does Oblak have a mammoth release clause, but his current contract isn't due to expire until 2023.

So it would essentially come down to Oblak actively ditching the opportunity to play guaranteed Champions League football in sunny Spain to risk his reputation in the harsh environment that is the Premier League.

Kepa with Chelsea

The only - and I mean ONLY - way this deal is ever going through is if Chelsea offer close to £100m plus Kepa to sign Oblak.

Why? Because it's a financial package that would surely be too good to turn down for Diego Simeone's side and the Blues could probably offer Oblak a substantial pay rise to get personal terms agreed.

But let's be realistic, even with Roman Abramovich's millions, that just isn't happening...
