Sebastian Vettel: Red Bull could challenge Mercedes in Monaco

Sebastian Vettel believes his Red Bull team could challenge Mercedes for victory at the next race in Monaco.

Mercedes have dominated the season so far, winning all five races, but the world champion believes Monaco's unique characteristics will help Red Bull.

Asked if they could compete with Mercedes there, Vettel said: "I think yes. It is difficult to predict but maybe in Monaco you need less power.You still need power, but maybe a little bit less than in other places."

Red Bull are being held back this year by their Renault engine, which team principal Christian Horner says is "80 or 90bhp down on the Mercedes".

The car itself is at least as fast as the Mercedes in the corners, which predominate on the tight and twisty Monaco street circuit.
