(Reuters) - Red Bull are seeking to secure Alexander Albon's Formula One return next season, with seats opening up at Alfa Romeo and Williams, while Mercedes are keen to place their new Formula E champion Nyck de Vries.

Albon, 25, drove for Red Bull's main team last year but lost his seat to Mexican Sergio Perez, who has now been confirmed for 2022. The British-born Thai has been racing in the German Touring Cars (DTM) series.
