Kimi Raikkonen and Antonio Giovinazzi will remain with Alfa Romeo in 2021, the team confirmed on Friday.
It will take Raikkonen, the 2007 world champion, into an 18th F1 season. The Finn, 41, holds the records for most races entered (327) and started (324) by any driver in the history of the sport and is the oldest on the starting grid. While another year for the Finn was expected, Giovinazzi's future had looked less certain.
The Alfa Romeo news opens the door for Haas to sign Ferrari junior driver Mick Schumacher, who had looked like the most likely candidate to replace Giovinazi. Schumacher, the son of seven-time world champion Michael, looks set to win the Formula 2 championship this season.
For Alfa Romeo, it means an unchanged lineup for a third straight season. The team's announcement said it "highlights the team's commitment to continuity".
Alfa boss Frederic Vasseur hopes the pair can help Alfa Romeo rise back up the grid.
