McLaren duo believe Monaco could be team's best chance

Outright power is less critical in the principality than elsewhere on the F1 calendar, but the fact that the MP4-30 chassis is consistent, and inspires confidence, is also important.

"I think already in Barcelona you will see a good step," said Button when asked by Motorsport.com.

"But we've got a lot happening before Monaco with the car, so hopefully there will be a good step, not just with the power, but also with the aerodynamic grip. I've got a good feeling about it.

"There are a few areas where the car needs to be stronger right now for Monaco, if we're going to go there tomorrow, but it will be an interesting place to drive this car, definitely.

"It's such a tricky circuit to find the limit, and if you have a car that you are confident in, it makes a massive difference.

"I remember Jean Alesi in a Prost doing a really good job round there because he had confidence in the car and the balance was there. It worked for him and it gave him confidence, and that's a thing that you need around there.

"You need it anywhere, really. Most drivers are talented, but it's a real mental game, especially at Monaco, because it's so unforgiving."

Alonso agrees the Monte Carlo race may be the best chance for his team given Honda's lack of power.

"Lower power effect circuits will help us at the moment," said Alonso. "So Monaco is the first circuit that we may enjoy a little bit of a better result.

"We'll see. I think we need to think race-by-race, and Barcelona at the moment is the first step."
