"Sebastian, it’s been an honour to call you a competitor and an even greater honour to call you my friend. You’re leaving this sport better than you found it which is always the goal. I have no doubt that whatever comes next for you will be exciting, meaningful, and rewarding. Love you, man."

Thank you for everything you’ve contributed to the sport we both love, I can’t wait for our last races together. Thank you, Seb - you’re an inspiration."
Ferrari driver and former team mate CHARLES LECLERC
"What a person and what a driver. We’ll miss you, Sebastian."

"It’s been an honour to share so many memories with you in Formula One. Looking forward to enjoying the last few races together in the paddock. Best of luck for your future challenges in life."
