The Scuderia have not won a race since the summer break, with their last success coming back in July at the Hungarian Grand Prix.
After Lewis Hamilton crashed out in qualifying, Ferrari now have a huge chance of overcoming the Mercedes team this weekend.
Bottas will be doing all he can to hold on to his pole position but Vettel is confident he has the pace to overcome his rival.
"Our long run looked good, especially compared to Valtteri, so let's see what happens," Vettel told Sky Sports F1.
"We are a lot closer than we were on Friday and I think tomorrow we should have a good race car."
Vettel's team-mate Kimi Raikkonen will start on the grid in third, with Red Bull's Max Verstappen just behind him in fourth.
