That is the opinion of ESPN FC pundit and former Major League Soccer star Alejandro Moreno.
Cech has come under criticism from some Arsenal fans for his performances this season.
The former Chelsea star was at fault for Swansea’s second goal in the shock 3-1 loss at the Liberty Stadium last Tuesday.
“It will be someone maybe but it’s not going to be Jan Oblak,” Moreno said.
“I think he has become a very important part of Atletico Madrid.
“He’s very well identified with Atletico Madrid as a club.”
“I think Oblak stays at Atletico Madrid.”
Oblak has made 96 La Liga appearances for Atletico since arriving from Benfica in 2014.
