Toro Rosso driver Daniel Ricciardo was delighted with his display in Friday's practice session for the Japanese Grand Prix.
Ricciardo, who replaces Mark Webber at Red Bull for next season, registered the 10th best time in the morning before finishing seventh fastest in the afternoon, and the Australian was satisfied with the outcome.
He told reporters: "I've been hoping to have a Friday like this one for a while now even if, of course, it's the Saturday and Sunday that's important.
"Today, we made progress with each change we made on the car, keeping each modification and then moving further forward."
Ricciardo is currently 14th in the drivers' standings with 18 points so far this season.
