Mick Schumacher's uncle has again questioned the "sense" in rumours the young German could move from Haas to Alfa Romeo for 2022.
Ralf Schumacher, the younger brother of 22-year-old Mick's father and F1 legend Michael, has already wondered if a sideways step on the grid is right for Mick.
"If it was a top team, it would be a great opportunity for Mick," Ralf told Sky Deutchland.
"But I'm not sure if Alfa Romeo really is a better option. Mick can still learn a lot at Haas, so if their new car really is a step forward, it would make perfect sense for Mick to stay another year.
"We can't forget that a young driver can need easily six months to establish himself in a team and get the most out of what he has. I think the collaboration with Ferrari is much more important for him.
"It seems to work well so far - even with his current team," Schumacher, 46, added.
