Quadruple world champion thinks it's possible for Red Bull to be unbeatable this season
Mar.16 (GMM) Alain Prost is worried 2013 could be a Red Bull whitewash.
Ferrari, Lotus and Mercedes all look competitive - Red Bull continues to lead the pack by a margin.
Quadruple world champion Prost told France's RMC Sport: "I hope there is no team or driver that crushes the opposition, as was the case two years ago with (Sebastian) Vettel.
"I'm a little worried about it, because - to me - the Red Bull looks very good."
Meanwhile, when asked to nominate a most dangerous rival for Red Bull in 2013, team boss Christian Horner told Spanish television Antena 3: "Fernando Alonso."
