Ferrari team principal Stefano Domenicali believes Fernando Alonso and Sebastian Vettel could "coexist" as teammates with the Italian Formula One outfit one day.
Vettel secured his second consecutive F1 title at Sunday's Japanese Grand Prix, and his contract with Red Bull expires in 2014.
Alonso, who won two F1 titles with Renault, has a contract with Ferrari through 2016.
Asked by the Gazzetta dello Sport whether Alonso would accept Vettel at Ferrari in 2014, Domenicali replied, "I think so, I think they could coexist. Fernando's strength is not being afraid of anyone."
Vettel has made no secret of his desire to race for Ferrari one day, saying after his Italian GP victory last month that the only thing that could have made it better "would be wearing a red suit."
