Jenson Button says it feels “surreal” to be returning to Formula One six months after his last race.

Button stepped down from driving at the end of last season but will return to McLaren’s race squad this weekend in place of Fernando Alonso,who is racing at Indianapolis.

“It feels slightly surreal to be back in the cockpit,” Button admitted

He insisted “there was no hesitation” when racing director Eric Boullier asked him about returning. “It’s a totally unique situation and a great opportunity.”

“I’m looking forward to stepping back behind the wheel for one of the most crazy, unpredictable and exciting races of the year.”

Button has not driven McLaren’s MCL32 but has familiarised himself with the car in the team’s simulator.

“Although I haven’t turned a wheel on track yet in the MCL32, I feel well prepared,” he said. “I know the track well, of course, and I’ve done quite a bit of work in the McLaren simulator already.”

“I’m still fit, and I’ve been training probably more than ever, because I’ve had the time to focus on my triathlon preparation and competitions. I’m looking forward to working with the team again, and, as I’ll be on the other side of the garage this time around, I’ll do my best to look after the car for Fernando.”
