Jenson Button believes McLaren could be helped by aerodynamics playing less of a role in the Monaco Grand Prix.

McLaren started the season in promising fashion but has since gone three races without scoring as the team struggles to get the MP4-29 working in certain conditions. However, Button believes there will be more emphasis on engine performance in Monaco which should play in to the hands of the Mercedes-powered cars.

"Obviously, I've never driven a turbocharged F1 car around Monaco before - and I'm relishing the opportunity," Button said. "More than any other 2014 race, I think this event will show us the most pronounced difference between 'old F1' and the new formula we have. There's far less of an aerodynamic influence here - it's just about bolting as much to the car as possible in a bid to find grip - so I think the engine's influence will be greater.

"So, with less significance placed on aerodynamics, I hope we can enjoy a better race than our two previous outings in China and Spain. Monaco is such a special case - in every respect - I just hope we can string together a good weekend: we'll need to get the absolute maximum from the car in qualifying and on the first lap to be in with a chance to put up a fair showing.

"I'm up for the challenge, and the whole team is doing a great job of staying strong and working flat-out to bring updates to every race - and Monaco is no exception."

And McLaren team-mate Kevin Magnussen believes he himself has some unfinished business at Monaco as he prepares to drive an F1 car there for the first time.

"My [World Series] race in Monaco last year was a bit of a missed opportunity," Magnussen said. "I didn't hook it all together and ended up finishing only fourth - so, more than anything, I want to have a clean and constructive race this weekend. We don't have the pace in the car to challenge at the front, but, wherever I am, I'm determined to make a fight of it."
