So with Ocon going to Haas I assume its:
Williams - Sainz, back up Ricciardo
Audi - Sainz back up Bottas
Alpine - Sainz back up Doohan
Mercedes - Antonelli, back up Sainz if he doesnt show enough.
RB - Lawson (maybe even mid season if danny ric gets announced to williams they might dump sargeant now and shuffle) - Hold on perez falling off a cliff
