Ferrari's Sebastian Vettel said that he felt 'very uncomfortable' during the race in Azerbaijan, after damaging his soft tyres early on during the first stint.
Vettel was unable to mount a serious challenge against the Mercedes' of Valtteri Bottas and Lewis Hamilton throughout the race. Vettel not being able to understand why Ferrari could not capitalise on their apparent pace advantage.
"The first stint was really poor, I struggled to get the tyres to work," Vettel told Paul DiResta during the post-race interviews. "I think the tyres were too cold and then when they were hot they were damaged, so it was never really working
"I was really uncomfortable and inconsistent and just couldn't feel confidence in the car. After that I was looking forward to a difficult stint on the medium tyres but they lasted to the end no problems."
Ferrari looked to have a decent advantage over their closest rivals Mercedes during this year's pre-season testing in Barcelona prior to the start of the season, but have yet to score a victory where Mercedes has made it four one-two victories out of four so far, with drivers Lewis Hamilton and Bottas taking two wins each so far.
However, despite being constantly ahead of Mercedes during the testing in Barcelona, Vettel believes that they can no longer be considered the team to beat when they return to Barcelona for the Spanish Grand Prix in two weeks' time.
"There's still plenty of work for us to do, we were not quite where we want to be", Vettel added. "On average we are not quite there. We are not the favourites going to Barcelona.
"The team is in good spirit. We need to chase them down. We are looking forward to a smooth weekend hasn't been that smooth but it will be crucial to catch them and turn things around."
