Sergio Perez thinks there is potential for some 'big surprises' at the United States Grand Prix, with qualifying and the race taking place on the same day.
Wet weather made it impossible for the FIA to allow qualifying to run on Saturday, and a decision was taken to postpone it until 9am on Sunday. The race is still scheduled to take place at 2pm.
With the weather forecast suggesting it could be a damp shootout for pole position and a dry race, Perez was one of many drivers expecting the normal competitive order to get shaken up.
When asked how mixed up things could get, the Force India driver said: "A lot. I think tomorrow we are going to see big surprises.
"There will be plenty of opportunities for many of us who probably don't have the most competitive cars out there. So there will be a lot of opportunities and we have to make sure that we can grab them."
Bottas sense chance
Williams driver Valtteri Bottas, who ended up fourth fastest in practice, was also expecting the potential for drivers to achieve more than they normally can.
"I think it will be a very interesting day, especially if qualifying is in the wet and the race is in the dry," he explained.
"It should be good. It is a day with a lot of opportunities, so I am looking forward to it."
His teammate Felipe Massa added: "I hope it will be competitive for us. It was a little bit of a boring day today, so tomorrow we have a lot of work with qualifying and the race on the same day.
"But I hope for a good day for the fans, who I think were not so nice for them today especially with conditions."
