Sebastian Vettel has once again admitted his desire to race a Ferrari in Formula One some day.
Fernando Alonso said a few days ago that Vettel, 24, is welcome at Ferrari.
"At the moment we are both bound by contract and I think both of us (are) happy in our teams," Vettel said in a joint interview with Spaniard Alonso for the German broadcaster RTL.
"But I have already said that I can imagine sitting in a red car at some point. So who knows?" he added.
Vettel is vying for victory on Ferrari's home soil this weekend but he said doing it with a team "with so much history" would be a "great feeling".
"In 2008 I had a little bit of that experience with the Italian team Toro Rosso and it was fantastic.
I hope I have many years in Formula One ahead of me so let's see what happens," he added.
Alonso, meanwhile, said he can imagine having Vettel as a teammate, even though both of them are regarded as the unofficial 'number 1' drivers at their respective teams.
"Why not?" he said. "At the top teams there is no one who does not want two good drivers.
But I have already said that I can imagine sitting in a red car at some point.
"It seems as though Sebastian is the number one at Red Bull but I do not say that. For Felipe and me it's the same; we race with the same conditions and during a season one or the other gets out an advantage.
"Viewed from the outside it's as though there's a team leader and a helper, but for the team it's best to have two top drivers because it increases the chances of winning the world championship," added Alonso.
