“Why not? I’m very open to anything,” said Alonso when asked about a potential move.
“I would be lying if I said I know what will happen next year.”
Ex-Formula 1 driver Marc Surer also believes IndyCar is an option for Alonso.
“Basically, there are only three ways for Fernando,” Surer told German television.
“He either stays at McLaren-Honda, he returns to Renault, or he does a full season in IndyCar.
“On the normal (Indy) tracks he would beat his opponents, and he has shown at Indianapolis that he can learn about the ovals.
“Alonso wants to win races again and he can most likely do that in IndyCar.”
