Vettel recovered to finish fourth in the race and slipped to a 34-point deficit against Hamilton with just five rounds remaining this season. But with Lewis Hamilton's Mercedes struggling for pace early on, Verstappen made a bold move up the inside of Turn 1 to take the lead on lap four, and he never looked back.
"There´s no doubt this session was also a tough moment for Ferrari, with Sebastian unable to take part, but there are no points scored on Saturday", said Wolff.
"We have some work to do", he added before flying to Japan to prepare for Sunday's race at Suzuka.
Vettel's afternoon was marred by a freak collision with Williams youngster Lance Stroll after the chequered flag, sparking fears of possible gearbox damage that could bring a grid penalty for next week's Japanese Grand Prix.
"We can not be distracted by the fact we got lucky again this weekend", said Mercedes team principal Toto Wolff.
"At the end of the second stint it was looking a little bit better for us but the auto was still having big problems at certain corners and I think Max was just managing the pace".
Vettel picked his way into the points with an impressive drive for Ferrari, who lost Kimi Raikkonen due to a battery issue before the race had even begun.
This leaves him 34 points behind Hamilton with 5 race left this season.Kimi Raikkonen, who was due to start second didn't even start the race, on account of turbo issues on his auto.
"There are some issues with the auto that we don't fully understand", Hamilton said.
"He drove a truly dominant race, making a sensational pass on Lewis and then really controlling the race from there".
"Ferrari had problems, but our race speed was comparable, because in the end Sebastian was on super-soft tyres, and you saw that when he was catching Ricciardo he went too close and he ruined his front tyres, so that's why he had to stop his attack", Marko said. How can we fix our issues? "I think in the beginning the auto felt good and I saw Lewis was struggling a bit with traction", he said.
"We can't really win a title this year but I think next year, if we don't win it, we have to really show strong signs that we can in the near future".
"This year I think we can just stay there or thereabouts".
