The Mexican is currently at the head of Ferrari's driver development programme. He was runner-up in the 2010 GP2 championship losing out to Wiliams' Pastor Maldonado.
But his debut season was better than the Venezuelan's as he scored 15 more points and ended in 16th place.
The Italian racing team has stuck with Felipe Massa for six seasons but in the past couple of years, the Brazilian has failed to win a single Grand Prix increasing speculation that 2012 could be his last season.
When asked about who was likely to replace Massa, he told Marca: "We will see as ultimately it depends on this year, which for me is very important."
"This season is yet to even start and everything changes very fast in a year. There are many things that are yet to have been seen," he said.
"For me, Ferrari is the greatest team for which all the drivers dream of one day winning the championship but ... let's see. I would love to be there some day."
Perez also knows that racing alongside Feranndo Alonso, Ferrari's main driver, would be a difficult challenge.
"Very difficult, I would say Alonso is the most difficult on all of the grid to have as your teammate, I respect him a lot," he insisted.
Perez does not fall in the same bracket as former world champion Alonso but he has the strong backing of Mexican sponsor Telmex and he is seen as a lucrative marketing tool in Central America.
"In these days you do depend more on your [financial] support," admitted Perez, "but I believe the talent remains the priority.
"Even with the drivers having support, I don't think there are any bad drivers on the grid.
"I was criticised a lot for coming with the Telmex money, but if you look back, a driver who wins five races in GP2 and loses the title by 10 points will normally go in F1 the next year.
"It (Telmex) is an influence, but to say it's why I'm here is not fair."
Current champion Sebastien Vettel is also known to be a fan of the Italian outfit but he is currently fully focused on winning a third consecutive drivers' championship.
