Jenson Button has downplayed the impact DRS will have on Sunday's Abu Dhabi GP, saying it will be "tough to overtake."
Last season's Abu Dhabi race proved to be a processional bore despite four drivers being in contention for the World title.
However, stuck behind slower cars and without a way to pass, the season finale lack the intrigue that many had been hoping for.
This year, to combat the problem, the FIA have set two DRS zones, however, Button fears even they may not do the trick.
"I think it's going to be tough to overtake with DRS," said the McLaren driver, who qualified third for Sunday's race behind Sebastian Vettel and Lewis Hamilton.
"Hopefully, we will have a different story tomorrow in the race.
"I don't want to finish third. So we will have to see but it does feel short still.
"Yesterday, I was DRS-ing out of turn seven all the way down to turn eight and I still couldn't overtake anyone.
"We will see how it goes, but yeah, hopefully there will be possibilities. It's a long, long race. There are a couple of pit stops, which will be important to get right
"We really don't know what's going to happen with the tyres but we know more than Seb, obviously."
