F1 pre-season testing 2021: Who's driving on Day 2 in Bahrain?

Day two of 2021 pre-season testing beckons and Fernando Alonso is set to make his long awaited debut for Alpine – but who else is taking to the track in Bahrain today?

Alonso missed Alpine's pre-season shakedown after a cycling accident put him in hospital, but the Spaniard is now fighting fit – though he revealed he still has titanium plates in his jaw – and will take over the whole day for his new squad after team mate Esteban Ocon drove on the opening day of testing.

Sergio Perez will also make his public testing debut for Red Bull – although he has already completed a shakedown run in the RB16B at Silverstone – after Max Verstappen opened testing for the team on Friday.

Mercedes, hampered by a gearbox issue on Friday, will share duties between reigning champ Lewis Hamilton and team mate Valtteri Bottas, while Aston Martin have Sebastian Vettel and Lance Stroll divvying up the day, and Friday morning leaders McLaren will do the same with Daniel Ricciardo and Lando Norris.
