Alfa Romeo will extend its Formula One stay into next season after announcing a new title partnership with Sauber.

The Italian brand first linked up with Sauber in 2018, and ahead of this weekend's Emilia Romagna Grand Prix in Imola, confirmed their association will continue for at least one more year.

It is expected that veteran Kimi Raikkonen, who recently surpassed Rubens Barrichello as the most-capped F1 driver of all-time, and his team-mate Antonio Giovinazzi will be retained for next year.

Alfa Romeo, powered by Ferrari, have endured a poor campaign and sit a lowly eighth in the constructors’ standings with just five points.

Frederic Vasseur, the team principal said: "The extension of our relationship with Alfa Romeo is a true statement of intent from both parties.

"In Sauber, Alfa Romeo found a committed, performance-driven partner to which they could entrust their brand.

"Both parties always intended for this relationship to bear fruit in the long term. We have laid some solid foundations in the last three seasons and we aim to reap the rewards of this work in 2021 and beyond."

The Alfa Romeo cars will this weekend run a one-off livery, incorporating the Italian flag, to mark the new deal.
