Gasly could not better 17th place in Saturday’s session, while his team-mate Esteban Ocon was one place and just 0.003s behind.
Gasly, who finished third in the rain-affected Dutch GP last weekend, admitted that the A523 simply wasn’t fast enough on Monza’s straights.
“Unfortunately, all weekend I was quite happy with the car balance, but we've just been two seconds off the pace the whole time,” he said when asked by Autosport about the team’s form.
“We knew coming here in Monza it would be the toughest weekend of the year with all these long straights. And yeah, it's clearly been the case.
“So we expected to be out in Q1. But you always have optimism that maybe with a hard tyre or something, you could get through, but that's all we had, unfortunately. A difficult weekend so far.”
Gasly actually had a tougher time on the hard tyre, which is mandated for Q1 under the Alternative Tyre Allocation (ATA) rules used this weekend.
“I think the hard tyre is probably the worst, I felt, of all,” he said. “I was really happy with the car on soft, pretty happy on medium, and with the hard, through corner balance has been just worse, and not going in the right direction for our car.
“Ultimately, you look at GPS, and it's very clear on where we're losing and yeah, we knew that we maximised everything we could, but the package doesn't suit the layout. I think we will have to analyse, review and come up with better solutions for next year.”
