Ferrari team boss Mattia Binotto expects Mick Schumacher to have a tough Formula One debut with Haas next year before getting more up to speed in 2022.
Schumacher, the son of Ferrari great and seven times F1 world champion Michael, won the Formula Two title this year and has graduated to the U.S.-owned team with close ties to Maranello.
Haas scored only three points this season and ended up ninth of the 10 teams.
"I think it will be very difficult for him at the start," Binotto told reporters in a video conference when asked what he expected from the 21-year-old Ferrari Academy driver.
