The Alpine driver picked up three five-second penalties for track limits offences over the course of the race.
He took the first at a pit stop, while the others were added to his race time, leaving him in 12th place behind the also penalised Sergio Perez and Lance Stroll.
“It wasn't a good day,” said the Frenchman when asked by Autosport about his difficult race. “I made too many mistakes with the track limits, and it cost me 15 seconds.
“So I can only be disappointed with myself because obviously, you're talking a few centimetres, which is nothing, but I paid a big price for it and missed out on the points. So I've just got to learn from this.
“All in all it was a tough day. I had a good start but went on the outside and had to slow down with the Mercedes [incident] in front of me, so lost another two positions.
“And then after that the whole race we had energy management issues, which cost me straight-line speed throughout the whole race. I was just trying to compensate for it, and took too many risks. So just not a good day from us."
