'I'm very mad about it' - Antonelli admits to 'unnecessary mistake'

World championship leader Kimi Antonelli said he was "very mad" about making an "unnecessary" qualifying error that left him starting the Azerbaijan Grand Prix from 16th on the grid.

The 91-point lead established by Antonelli at the top of the standings with nine races remaining has put him in a position where merely solid results will see the Italian to a maiden title.
