Should the Finn call time, Perez, who raced with the team in 2011 and '12 when it was formerly known as Sauber, is likely to appear close to the top of the list of potential replacements.
Team principal Frédéric Vasseur, however, is a known fan of free-agent Nico Hülkenberg. The German revealed after his two-race Silverstone cameo he had made contact with the team about a potential drive.
With only one seat potentially up for grabs, and this is if Raikkonen leaves, how would you choose between the two?
Despite a recent podium finish in Mugello, Albon has struggled to match his team-mate in his first full season alongside the Dutchman.
Red Bull would ideally see Albon pick up the pace and act as a rear gunner for Verstappen and all the signs point to the team giving the Thai-British driver more time to achieve this target.
To AlphaTauri then, and this looks like another case of 'no room at the inn'.
Pierre Gasly is almost certain to remain. After scoring his maiden win at Monza, the Frenchman has turned a corner since being relegated to the junior team midway through 2019 and is, if anything, putting pressure on Red Bull to again consider switching him and Albon.
The second seat is a close contest between Kvyat and F2 driver Yuki Tsunoda. The Japanese talent is not only part of the Red Bull junior programme but is also backed by power unit supplier Honda, although its announcement it is pulling out of F1 at the end of next year may have altered that landscape.
While a move to Red Bull may be an attractive option for Perez, with five drivers already vying for four seats, it is not easy to picture where the Mexican fits in.
IndyCar, Formula E, WEC...there are options outside of F1
As difficult as it is to imagine, there is life outside of F1. Jean-Eric Vergne, Sebastien Buemi, Nelson Piquet Jr. and Lucas di Grassi have all taken world titles in Formula E after leaving F1.
Countless more have gone on to achieve success in other categories, including two-time Indianapolis 500 winner Takuma Sato.
So often it feels as though the loss of an F1 drive is the kiss of death for a driver's career, but this is not true.
Should Perez leave the F1 paddock, it would be a shame, but it would almost certainly not be the last we hear of the Mexican.
