Sebastian Vettel believes the "scrappy" nature of his second practice session for the Monaco Grand Prix has masked Ferrari's true pace.
Vettel was only ninth fastest during Thursday's second session around the streets of Monte Carlo, as the German also had two brushes with the barrier.
Vettel spun at Mirabeau Haute and backed into the wall, before later clipping the barriers as he exited Sainte Devote.
"It was not a "clean" day in the office today," he admitted.
"Our session was a bit scrappy: I touched the wall, damaged the rear wing, but luckily we were able to fix it and carry on.
"I just didn't get everything out of the car, couldn't find the rhythm and didn't do good laps on the Ultra Soft tyres.
"If you look at the standings, we don't belong where we scored today. But overall the car is good and has the pace. So I am not worried for Saturday.
"Today our focus was not towards ranking high up, we tried a couple of things and it is fair to say that some of them didn't work. Being the first practice day, it is also difficult to see what other people did."
