Daniel Ricciardo-Sebastian Vettel

Red Bull driver Daniel Ricciardo believes his teammate Sebastian Vettel will be "really hungry" for success in the 2014 German Grand Prix.

The defending champion has a poor season so far and sits sixth in the driver's championship table, 95 points behind leader Nico Rosberg and 28 behind his Red Bull teammate.

Ricciardo is aware of Vettel's potential and has backed him to come good in front of his home fans during this weekend's German Grand Prix.

"I don't know if the word is improve or get better because he is already very good, but I'm sure his form – if people are calling it that – is going to come, or it has come," Ricciardo told Sky Sports.

"So Germany I'm sure he's going to be really hungry to show his home that he's ready to take it on. For me it's just trying to improve, keep doing what I'm doing. Obviously I'm excited if there is a bit more in him because I think that'll bring out a bit more in both of us."

"So let's see. I know Germany he will be hungrier than ever so it should be a good battle on our hands," the Australian driver added.

Vettel's form has been so poor in this year's Formula 1 that he is the second best driver in Red Bull, behind Ricciardo. The Australian driver believes long straights at Hockenheim could make it difficult for Red Bull during the German Grand Prix.

"There's a few long straights there [at Hockenheim] so on paper it's probably not the circuit that suits us the most to be honest," Red Bull's leading driver this season admitted.

"Third sector [of the lap] in the Germany should probably be good for us, but in the first two we'll probably leak a bit of time. But let's see how we go. Budapest we can be a bit more optimistic for," Ricciardo concluded.
