Alfa is keeping it's current driver intact for the 2020 season. They've signed Antonio Giovinazzi to partner with Kimi once again.
“I am very happy to be staying with the team for 2020," the 25 year old Italian driver said. "I am grateful for the incredible level of support I received in my first full season in Formula One: everyone in the team has stuck by my side since I joined and I am really looking forward to continuing our journey together. We learned a lot this year and I am confident we can make a big step forward next season. I won’t be a rookie anymore so there won’t be any excuses for me: I want to be competitive right from the start of the championship and repay the confidence the team has shown in me.”https://www.sauber-group.com/motorsport/f1-news/alfa-romeo-racing-and-antonio-giovinazzi-to-continue-together-in-2020/
