McLaren racing director Eric Boullier has no concerns about Jenson Button's fitness after he was announced as Fernando Alonso's replacement in Monaco.
The Woking team confirmed on Saturday morning that the 2009 World Champion would be ending his sabbatical for one race only as Alonso heads to the Indianapolis 500 to try and secure the second leg of the prestigious Triple Crown.
And Boullier is looking forward to working with Button again, labelling him a "class act".
"I was truly delighted when Jenson accepted our suggestion that he race at Monaco instead of Fernando," said Boullier.
"And I know I speak on behalf of everyone at McLaren-Honda, and all our sponsor-partners and fans too, when I say that it’s great news for Jenson, for McLaren, for Honda, for our sponsor-partners, for Monaco, and for the sport of Formula 1."
"Jenson is a class act. He’s a superb driver – fast, smooth and precise – and he won’t have lost any of his competitive edge over the past few months.
"After all, he’s missed only a handful of Grands Prix since his last outing in Abu Dhabi in late November last year, and he’s as fit as a fiddle.
"Also, he’s always been good at Monaco. He’ll do a great job for us, I’m sure of that.
Boullier also reiterated that Alonso will return to the team for the Canadian Grand Prix.
He added: "Fernando will be back at the wheel of the McLaren-Honda MCL32 in Montreal, and I hope he’ll have some great stories to bring back to us from Indianapolis.
"You couldn’t get two more different racetracks than Monaco and Indy – one of them a twisty and bumpy street course and the other a mega-high-speed banked super-speedway bowl – but that’s the beauty of our sport.
"It also reflects the technical versatility of McLaren and Honda. And it underlines the fact that we’re racers, above everything else."
