Vitaly Petrov on Tuesday named three leading contenders to become his new teammate for 2011.
After visiting his injured teammate Robert Kubica in an Italian hospital, the Russian named "(Bruno) Senna, (Tonio) Liuzzi and (Nick) Heidfeld".
Petrov was speaking at the Santa Corona hospital, quoted by ivg.it.
"We were with him for about a quarter of an hour. We joked and found him very well," said Petrov, who was with their Renault team boss Eric Boullier.
"Of course he immediately wanted to know the team schedules for the season. Meanwhile we will look for his replacement.
"The team is close to Robert and we are waiting with open arms and hoping he can return by the end of the season," he added.
Kubica will have surgery on his shoulder and foot this week, to be followed by an elbow operation.
