“It was a stupid mistake. Mark came to see me after the race and was obviously
not happy, but I apologised and we have to move on,” he said.

“I’ve sat down and looked at things again with the team, for sure it’s still
an area we need to improve. We’re clearly focusing on this area for the next
races.”

Grosjean was given a 10-second stop-and-go penalty in the pits in Japan and
retired from the race towards the end when it became clear he was out of the
points.

Red Bull’s Webber had to scramble to rejoin the race and then made a pit stop
for running repairs, returning at the back of the field before racing hard
to finish ninth.
