Mark Webber has said he expect the 'main teams' to emerge on top of the pile through the remainder of the F1 season despite the wide open start to the 2012 campaign.

Five different drivers from five different teams have taken victory so far this season in one of the open seasons seen for some time, partly because of the unpredictability that has come from the new Pirelli tyres.

Speaking ahead of the Monaco Grand Prix, Red Bull ace Webber said that different people would have differing views on whether the unpredictability was good or not, although he said he expected the usual suspects to be the ones fighting for honours when the season ends.

"It depends on who you are," he said. "I think for the purist, I think people are taking a little bit of time to get used to it. Obviously, no one's really got any momentum yet in terms of results in teams. But obviously there are a few people that follow the sport that love it like this. It depends who you ask. If you want to have lots and lots of different teams being competitive that's the way it is at the moment, which I don't think is too bad. But let's see. I think ultimately the main teams will still do well at the end of the season."

Webber added that the change to Pirelli tyres has been one of the biggest changes made during his time in the sport, given the way in which drivers are now forced to drive to deal with the tyres provided.

"The way the races have run in the last few years is different to previous years," he said. "In the era where we had pit stops with refuelling, the races were extremely aggressive. Obviously qualifying for the whole race, basically, pushing to make optimum strategies work and make sure that you're hitting the lap times with the weight of the car, with the fuel that you have at the time, so whether you are on a two- or three-stop strategy or whatever.

"Then we went to no refuelling, so already the phase of the racing changed a little bit, in terms of a little bit of endurance aspect started to come into it, in terms of driving style and pacing yourself a little bit more, probably. Then we had the change with the Pirellis and that's probably been the biggest change in driver technique and style that I can remember, certainly in my career and I've done a few Grands Prix.

"There are certain races...when the winners are not driving at 100 percent and that's just the way it is, because you can't. You need to get the car to the end and produce the best lap times that you can for the duration of the race. That's the way it is now. I still enjoy driving a Formula One car, I still love working with the engineers, driving the most amazing tracks against some great opposition. I enjoy that part of it but we always have to change, we always have to evolve as the technical side of the sport changes, and there's always going to be nicer ways to...

"Personally, I enjoyed the sprint races and the refuelling, probably all of the drivers did, but the racing was not super-exciting. It was more precise, you had to be more precise, you had to be more on the limit and really really feeling the car for the whole two hours, but that's not how it is now. We have a different set of challenges and that's what we've got to do."
