Max moans not down to tire trouble

RED BULL LOSING NO SLEEP

- Daniel Moxon

RED BULL have rubbished accusations of unprofessionalism towards Max Verstappen following the world champion's bad-tempered outbursts in Budapest.

The Dutchman finished only fifth on Sunday after moaning constantly about his car, the team's "s***" strategy and then Lewis Hamilton, after the pair collided while he pushed for the podium.

Angry radio messages are hardly out of character for the three-time champion but his complaints in Hungary pushed race engineer Gianpiero Lambiase to snap back at him more than once.

Sky Sports F1 commentator David Croft pointed during the race that Verstappen, 26, had been up until 3am the night before sim racing in the virtual 24 Hours of Spa.
