"I need to be careful now!" said Vettel when asked whether he'd prefer Alonso or Kimi Raikkonen alongside him in the team. "Nothing against Fernando, I respect him a lot as a driver, but I think I respect Kimi on-track, off-track because he's always been very straight with me.
"From that point of view it might be a bit easier," he said. "I'd prefer Kimi."
Previous rumours suggesting that Vettel might be contemplating a future swap to Ferrari have usually been dismissed on the basis that Alonso would used his reported contractual right of veto over the selection of his team mate, as the Spaniard is thought to be keen to avoid another uncomfortable season such as his last at McLaren where he struggled to stamp his authority on a rookie by the name of Lewis Hamilton.
The latest rumours seem to have significantly impacted Daniel Ricciado's hopes of ascending to the Red Bull seat from his present berth at the junior Toro Rosso team.. The young Australian disappointed in the Hungarian Grand Prix, finishing behind his current team mate in 13th place a full lap off the leaders.
With the decision over who will replace Mark Webber expected to be taken over the summer break in August, this was Ricciardo's big chance to impress the Red Bulls powers to be that he was ready for the opportunity, and the way things went on Sunday may give Horner and the rest of the Red Bull team management pause for thought and sending them in the direction of more experienced pair of hands for what will be one of the plum seats on the 2014 F1 grid.
And when it comes to experience and talent, it doesn't get any better than weighing a choice between former world champions, and Horner reiterated this weekend that the team was in no hurry to make a final decision.
“We are starting to get a clearer picture but then other options pop up. We are in fortunate position where we are not in a rush,” he said. “We have a great deal of interest in the seat and we just want to make sure we get it right.”
