Sergio Perez admits he is now up against it understanding his new McLaren
Mexican needs dry running to work on set-up

The Mexican completed exactly 100 laps on Thursday as F1 reconvened at the Circuit de Catalunya for its final pre-season test but was left frustrated as cold and wet conditions once more held sway.
Perez spent most of the day running on either full wet or intermediate tyres and said he would much rather have lapped in dry conditions. The 23-year-old now has just one more day behind the wheel before the Australian Grand Prix in just over a fortnight's time.
"It was a very productive day and a very important day, to get to know the car in those conditions - in the wet conditions and the inter conditions," Perez said.
"In that area it was a good day, but obviously I would like to have a dry day and do the work we've prepared to do."
Perez's expression of concern comes in the wake of comments made last week by Jenson Button, who admitted he was finding it difficult to understand the MP4-28's behaviour at times in response to set-up changes.
"I cannot tell you that we have learnt such an amount on the set-up because basically today we didn't learn anything about set-up. What we learnt was about the tyres and how they behave - the crossover from wet to inters," Perez continued.
"From that point of view, it was important. But on the set-up, I think there is a lot of work to be done in the next couple of days."
Perez is due to run again on Saturday, when dry weather is forecast. He added that, besides set-up, gauging the effectiveness of upgrades McLaren have introduced this week is the priority.
"I would really like to learn about the updates, we have some updates on the car - about the set-up, to get comfortable with the set-up because the last day I was here, I was not comfortable with the set-up I had," the former Sauber driver added.
"We've done some changes and obviously I'd like to try them before Melbourne. But if I don't get the opportunity to try them then I'll have to look forward to Melbourne and there's nothing else we can do."
