Red Bull driver Daniel Ricciardo has said that he is confident of having a "good weekend" at the Chinese Grand Prix.
The 25-year-old finished third in the second practice session at Shanghai International Circuit, finishing just over a second slower than leader Lewis Hamilton.
"It was definitely a positive day for us. We did more laps and more understanding with those laps. I think on both tyres, also short and long runs we're pretty happy," Sky Sports News quotes Ricciardo as saying.
"We had new parts on the car; they all seem to work, so that's good for now.
"I definitely feel more confident. Even my satisfaction when driving the car this afternoon: I felt the grip; I really feel the improvements that the car's made, so that's always nice. I'm positive it can be a good weekend."
Ricciardo finished sixth in the season-opening Australian Grand Prix, before ending in 10th place in Malaysia last time out.
