Daniel Ricciardo says Red Bull is "pretty close" to where it wants to be following Friday's practice sessions for the Austrian Grand Prix.
Ricciardo, who celebrated his 27th birthday on Friday, was fifth quickest during both sessions as Mercedes' Nico Rosberg led the way.
Red Bull has struggled at its home event since the circuit returned to the calendar in 2014 but Ricciardo is optimistic over its potential this weekend.
"I think we’ve had a pretty good day and didn’t fight the car too much today," he said.
"This morning we got up to speed pretty quickly, which was important.
"Then this afternoon was crazy. The level of rain was really high during the session, but it was actually good to experience two different conditions.
"The rain was so local and came in really hard at Turn 8 and 9 so that part of the track was especially tricky. If in the race you get that part of the track first before the others then you could be quite unlucky.
"It’s been a track where we struggled a bit in the past, but I felt pretty comfortable from lap one so I think we are more or less there and won’t be here until midnight tonight trying to find a set up.
"We are pretty close to where we need to be so that’s a good start. If it rains tomorrow then anything is possible. It’ll be very interesting."
