Speaking ahead of his debut with the team, Sainz said from his experience in moving from team to team, it’s hard to be completely ready by race one.
He said; “My intention is obviously to be 100% ready for race one.
“But realistically speaking from my experience changing teams during all these years has been that that is very difficult to achieve.
“There’s always experiences, feelings that you need to go through race-by-race, or race weekend by race weekend, in free practices, in qualifyings, in the races that you always end up learning during the races rather than testing.
“One day and a half of testing per driver is not going to help (much).”
Ferrari will launch their new season contender on March 10, ahead of pre-season testing in Bahrain on March 12.
