Pepe Reina is good enough to fill Valdes' shoes claims international team-mate Fabregas.
Valdes is set to depart after 11 years at the Camp Nou, increasing speculation about a possible replacement for the Catalan.
Reina, who is currently on loan at Napoli from Liverpool, rose through the youth ranks at Barcelona's famed youth system.
The Napoli 'keeper, who has represented the national team 29 times, has long been tipped to replace Valdes.
Fabregas insists it will be weird to see someone else in goal for the Spanish Giants when the time comes.
"Victor has been here for 10 years and none of us can imagine another goalkeeper in his place when we turn and look at our goal," Fabregas told Radio Catalunya.
Fabregas, who joined Barcelona from Arsenal, believes his international teammate could be the one to replace their out-going 'keeper.
"But one of the things that Pepe can bring is that he knows all of us. He provides a very good atmosphere in the dressing room and is experienced."
Fabregas, who returned to Barcelona in a deal worth £35 million plus £5m in add ons, has become a regular under new boss Gerardo Martino, appearing in 13 games this season for the Catalans.
Reina left Barca's academy to join Vilarreal before joining Liverpool in 2005.
