High degradation on the soft Pirelli tyres was the greatest cause of concern for the drivers during Friday's practice sessions and there is a feeling among the experts that most of the teams will go for long-lasting medium tyres in tomorrow's final race.
"What is the right strategy we will find out tomorrow. The race is long so we will have plenty of time to make up and adjust the strategies," said Vettel, who positioned himself perfectly for a fourth straight world title after securing his third consecutive Indian Grand Prix pole position here today.
"I really like the circuit specially the middle sector is very challenging with fast, high speed corners. The car has been very strong since yesterday morning. We didn't have to adjust that much. It was a good result for me as well as for the team with Mark sitting on the fourth spot," Vettel said.
Rosberg, meanwhile, admitted that medium tyre strategy is a consideration for tomorrow's race.
"Medium tyre was always a consideration (for today). It is a consideration for tomorrow but today we decided that soft tyre was the best way to go. It was the best thing to do from my point of view. But medium tyre strategy is also good one," he said.
