Ricciardo qualified 15th and eventually finished 14th of the 17 cars still running at the chequered flag, having struggled for grip for much of the race.
With his team-mate Yuki Tsunoda retiring, the race was the first time in four events that the Faenza outfit failed to score, having previoulsy narrowed the gap to seventh-placed Williams to just seven points.
“I was coming into the race optimistic,” said Ricciardo when asked about his race by Motorsport.com. “There was still a bit of a reality that maybe it will be okay, maybe it won't. Unfortunately, maybe it wasn't.
“We knew [in] the race starts and restarts we would struggle, because we've definitely missed something here this weekend, getting the tyre working on the slippery asphalt when it's still cold, or a new tyre.
“But even with that, I felt, 'okay, after a couple laps, we'll get some temperature and then be able to kind of get back on to the pack'. But we never really got there. And I think the restarts didn't help us.
“But that's not an excuse. It's just something that we lacked this weekend, we really struggled at the start of stints.
“Once it settled, there were a few cars fading at the end of the race. So we had a little bit more pace than them. But we still weren't a top 10 car. So, unfortunate.”
