McLaren Having A Tough Start To Formula 1 Pre-Season Testing

Two-time champion and McLaren driver Fernando Alonso lost control at the last corner of Barcelona's Circuit de Cataluña when his right rear wheel came off at the Formula 1 pre-season testing.

Red Bull's Daniel Ricciardo set the fastest time ahead of Mercedes' Valtteri Bottas. Alonso and McLaren recovered to set the seventh fastest time of the day. McLaren blamed a "wheel nut issue" and Alonso lost valuable running in the best conditions.

Alonso was initially classified fifth but was demoted to seventh when it was confirmed he had cut the chicane on his fastest lap to ensure he was not delayed by Toro Rosso's Brendon Hartley.
