Button expects Dennis's overhaul of McLaren F1 team to pay off

Dennis was appointed as McLaren's Group CEO earlier this year with a mandate to review the F1 team's operations to prepare it better for the future.

He has already taken action in appointing Boullier as racing director, and deciding that the F1 team will appoint its own CEO at some point in the future.

Jonathan Neale is fulfilling that CEO role in the interim period, while the future of team principal Martin Whitmarsh is in doubt although there has been no official news on him.

Button thinks that Boullier's arrival will be important in delivering some fresh momentum to McLaren, and reckons that, when the final positions are finalised, the team will be well set.

"I think it's good to have fresh ideas, and I think he [Boullier] does add to the team," explained Button.

"The team will never be changed by one individual, but I think he does add something. And when the management structure is complete we'll be in good shape."

Button said he had not had much contact with Boullier prior to his arrival at McLaren, but had been impressed with what he had seen the Frenchman do at Lotus.

"I don't know the way that he works," said Button. "Obviously Lotus have had a very interesting and exciting last few years.

"Last year was a very difficult year for the team, with what was going on in the background and it looked like he controlled that issue reasonably well."
