Suzuka: Mclaren messed up with their tactics in their qualifying session for the Japanese Grand Prix, driver Jenson Button said on Saturday.

Button qualified 16th at the Suzuka circuit, although he reckons he might have made it out of Q1 but for the yellow flags which came out towards the end of the session when Max Verstappen's Toro Rosso stopped on the track.

Button was particularly displeased with the team's failure to communicate a message to switch the engine mode on his car ahead of his first flying lap.

"There was a yellow flag in the middle sector so obviously I had to lift. Without that I probably would have got through," he was quoted as saying by Sky Sports after the qualifying session.

"On my first run I wasn't told what engine mode to be in - every time before our timed lap we're told before we start - and I wasn't told. So I went to the wrong setting and it emptied the pack after half a lap."

Button also said the intense competition among the teams means that any errors will be punished even more than usual.

"The car didn't feel too bad to drive, but you need to get everything out of it; you can't make a single mistake. Even getting the front wing just half a turn out; everything has to be right," he added.

"Then you have a chance of doing something at least. We definitely messed up today."
