McLaren chief QUITS: F1 team undergo drastic overhaul after poor 2018 season
McLaren were hopeful at the beginning of the season that they would be able to drastically improve their run of poor performances over the past few years.
Both Fernando Alonso and Stoffel Vandoorne finished inside the top 10 in the first two races of the campaign, but have only achieved that four times in the seven Grands Prix since.
The last four races have been particularly worrying for McLaren with Vandoorne only finishing 12th or worse while Alonso has been forced to retire twice.
It means they currently sit sixth in the 2018 Constructor standings and they have taken the decision to revamp the backroom staff with Boullier resigning from his role.
