Sergio Perez will not necessarily simply return to Sauber in 2014, boss Monisha Kaltenborn insists.
The Swiss team was disappointed late last year, when Perez was signed by McLaren.
Sauber continued to wear Telmex branding in 2013, but fellow Mexican Esteban Gutierrez had been promoted from the reserve role.
Two Mexicans for 2014? Perez and Gutierrez wouldn’t mind.
"Mexican power!" Gutierrez said on Thursday. Perez agreed: "I think it would be good. Why not?"
Two Mexicans in a single team might appear untidy for a Swiss F1 team, but Kaltenborn said Sauber has "never chosen drivers by nationality".
The team has also been struggling financially in 2013, so might not be in an ideal position to be too choosy.
When asked about Perez, Kaltenborn was quoted by AS newspaper: "We had a good relationship, and good memories of his years here.
"But there are other drivers who could be on the team," the Sauber chief added.
The ball would appear to be in Telmex’s court, particularly after McLaren changed direction so radically by ousting Perez.
"The money is there to run both of them (at Sauber)," an unnamed Mexican was quoted in Austin by AS correspondent Manuel Franco, "and even to buy the team."
