Former Atletico Madrid captain Gabi says it's critical they keep hold of Jan Oblak.
The goalkeeper is being linked with PSG this week.
"[Oblak] provides points for Atletico Madrid and finding a goalkeeper that can do this is very important," Gabi told COPE's El Partidazo show.
"I think that Atletico will make an effort to make him stay, and hopefully he wants to stay.
"He is decisive and Atletico must have a goalkeeper like Oblak.
"I am sure that he would like to have renewed by now; I have no doubt that they will reach an agreement."
