A new documentary has revealed McLaren had genuine fears Fernando Alonso would quit on the eve of the 2017 season and cause a domino effect which could destroy the team.
Amazon's 'Grand Prix Driver' follows the progress of McLaren during the early stages of 2017, when it started to realise the scale of the problems with Honda's engine. It was the third consecutive season the team was delivered an underpowered and unreliable power unit, ultimately leading to the split from Honda later in the year.
According to Motorsport.com the documentary, due for release on February 9, reveals just how worried McLaren bosses were that Alonso would have finally found the limits of his patience and simply decided to call it a day.
