After winning three out of the seven races so far this season and topping both championship standings, Red Bull's dynamic duo of Sebastian Vettel and Mark Webber must be looking mighty tempting to any number of rival teams on the grid. But the most alluring, according to recent reports, could be Ferrari.

For his part, Vettel is widely regarded as the personal favorite of one Bernie Ecclestone, who could be helping to broker a deal that would see the young German wearing red in the near future. Vettel, however, is on a long-term contract with Red Bull, leaving the possibility open for a few years from now.

More likely for the near future, however, could be Webber. The 33-year-old Australian driver – fresh from back-to-back victories at the Spanish and Monaco grands prix – is on a year-to-year contract with Red Bull, which could leave him free to switch teams in the off-season. Red Bull chief Christian Horner has hinted at his intention to retain the driver currently topping the standings, but until a contract is signed... mind you, contracts in F1 aren't worth what they once were.

While Fernando Alonso continues to impress, Ferrari is widely speculated to be dissatisfied with their second driver Felipe Massa, and could cut the Brazilian lose for next season. Alternative reports place Renault's Robert Kubica in the Scuderia's hot seat, but only time will tell.
