Jack Doohan is “not good enough” for Formula 1 and made far too many mistakes early in his career, according to veteran racer Ralf Schumacher. Alpine rookie Doohan was benched by the team after last weekend’s Miami GP, with Franco Colpainto taking his place in the A525 cockpit for the next six rounds of the season.

Colapinto’s arrival came after Alpine opted to sideline Jack Doohan, just seven races into his F1 career. The Australian rookie suffered costly crashes in Melbourne, Japan and most recently in Miami, triggering Briatore to make a change.
