Valtteri Bottas has signed a new deal with Mercedes, keeping him at the Formula One team until the end of the 2021 season. Next season will mark Bottas' fifth campaign with the Silver Arrows.

Bottas, the overall runner-up last year, joined Mercedes in 2017 and has so far notched eight wins and 12 pole positions with the team.

The 30-year-old, who won the opening round of the season in Austria, said: "I'm very happy to stay with Mercedes in 2021 and build on the success we've enjoyed together already."

"The past few years have been all about continuous improvement, working on every aspect of my performance," he added.

"I'm confident that we have the strongest driver pairing in F1 today and signing Valtteri is an important first step in retaining this strength for the future," said team boss Toto Wolff in a statement ahead of the 70th Anniversary Grand Prix.

Mercedes are also expected to continue with six-time world champion Lewis Hamilton, who is out of contract at the end of the year.

Hamilton is leading Bottas by 30 points after four races and is going for his fourth successive victory on Sunday when Silverstone hosts a Grand Prix for the second weekend in a row.
