Red Bull, Renault, eye team switch for Buemi

Sebastien Buemi has leapt into contention for a move to a better team in the future.

With the backing of owner Red Bull, the 21-year-old Swiss currently drives for Toro Rosso but is hoping to eventually graduate to the energy drink company's main team.

The Swiss daily newspaper Le Matin said Buemi currently has no contract for 2011, but has attracted the attention of rival team chiefs with his driving at recent races.
