Finland’s Valtteri Bottas will continue with Mercedes for 2019. The Finn, who has had some shocking luck so far this season, has penned a new one-year deal with an option for 2020 if he continues to do enough to keep his seat. 

Bottas: "It is great news that I will be racing for Mercedes in 2019 and it is nice to announce it here in Hockenheim - not just the home race for Mercedes but also the circuit where I took my first ever single-seater wins back in 2007." 

"This year, with a full winter of preparation, I have been able to make a good step forward - and I believe that there is still more to come. We have not been so lucky in the races this year but the team knows how I am performing, and this is a great sign of confidence in me and my driving." 

"I enjoy working with the team, and also being team-mates with Lewis - we have a good relationship, honest and straightforward, and always aiming to get the right results for Mercedes." 

"We have a big battle on our hands right now, so it's good to have the future clear for everybody - it means we can have a full focus on the championship fight." 

"Obviously, my goal is to keep performing at a high level - and to make it a no-brainer for the team when it comes to deciding their plans for 2020 as well." 

Toto Wolff: "We are very pleased to extend Valtteri's contract with Mercedes for another season at least - and to be able to confirm an unchanged driver line-up for 2019, ahead of our home race in Hockenheim." 

"Valtteri's performances have been excellent this season and, if not for our mistakes and his misfortune, he could be leading the drivers' championship at the moment." 

"When we took the decision in favour of Valtteri for 2019, it wasn't just about his undoubted speed and work ethic, but also a question of character. His relationship with the team, including Lewis, is open and trusting, without any politics at all." 

"Those are the ingredients you need when you're fighting strong rivals in both championships and they mirror the values inside the team. I am very excited to keep Valtteri in the team and look forward to celebrating many more successes with him." 

On Thursday, Mercedes released a statement saying that Lewis Hamilton signed a new two-year deal with the team which will run until 2020. The four-time champion has been with the team since 2013. So far, he’s won three of his four drivers' titles during his spell with the Brackley team.  

Hamilton: "This contract extension has basically been a formality since Toto and I sat down during the winter, so it's good to put pen to paper, announce it and then get on with business as usual." 

"I have been part of the Mercedes racing family for 20 years and I have never been happier inside a team than I am right now." 

"We are on the same wavelength both on and off track - and I am looking forward to winning more in the future and shining even more light on the three-pointed star. I'm very confident that Mercedes is the right place to be over the coming years." 

"Although we have enjoyed so much success together since 2013, Mercedes is hungrier than ever - from Dr Zetsche and the board members at the top of Daimler, through Toto and the team management, to every single person I meet in the corridors of Brixworth and Brackley." 

"The competitive passion that burns bright inside me is shared by every single member of this group - always chasing the next improvement and digging even deeper to make sure we come out on top. I can't wait to see what we can achieve together in the next two-and-a-half seasons." 

Wolff: "We have been aligned with Lewis ever since we first sat down to discuss the details of this contract after last season, but there has understandably been a lot of interest and speculation around the whole process, so it's good to put all of that to rest and get this thing announced." 

"We signed the final documents this week and didn't want to keep people waiting any longer! There is not much about Lewis as a Formula One driver that hasn't been said already - he is one of the all-time greats and his track record speaks for itself." 

"But what I enjoy most about working with him is getting to know the man inside the racing helmet: his relentless drive for self-improvement, his emotional intelligence as a team member and his loyalty to those around him." 

"Mercedes has become Lewis' home in Formula One and his story is linked forever with the silver and green of Mercedes-AMG Petronas. I am very confident that we have some incredible chapters of our story together still to come."
