Daniel Ricciardo concedes Red Bull are struggling for grip around the streets of Baku after a difficult first two practice sessions for the team at the European Grand Prix.
Ricciardo was 13th in first free practice on Friday, three seconds behind Lewis Hamilton at the top of the timesheets.
The Australian did not manage much better in the second session, finishing 10th with a gap of over two seconds to the Mercedes at the top.
Red Bull are hoping to improve on their lap times before Saturday's qualifying session, with grip their biggest issue around the Baku City Circuit.
"We are still chasing some grip. [We are] not as close as we'd like to be," Ricciardo said. "Obviously we will say that, but we have some work tonight.
"Getting the tyre to really dig in and get into that new, oily tarmac is not so easy.
"We feel that if we find a way to sort of make that work a bit better we'll find a good chunk of laptime."
Ricciardo's morning session was cut short by becoming the first Formula One driver to crash into the barriers of the new track in Azerbaijan.
"I actually didn't brake that late," the 26-year-old explained. "I think I came off the brakes too quick and basically tried to carry too much speed across the corner.
"I didn't think there was a problem but then I realised I just carried too much speed, so the rear kicked out."
Bit of a clip of the ol' barrier today. Nothing a good bunch of mechanics couldnt fix. Some speed to find tomorrow but we're workin on it-- Daniel Ricciardo (@danielricciardo) June 17, 2016
