Zhou says he is already building good chemistry with Finnish veteran Bottas, 32, who arrives at Alfa Romeo from Mercedes after five years alongside seven-time world champion Lewis Hamilton.

"The Alfa Romeo car feels great. Each car is different, and I'm adjusting to the new car quickly. All the tests have gone smoothly so far, and the pace and times have been better than the team's original expectations. I feel I fit in pretty well," said Zhou, who began testing earlier this month.

"I know next season, the car will feel totally different as there will be big changes next year. But it's not a problem for me to get used to the new car. I'm very positive about next season.

"I've already had a lot of interaction with Valtteri during testing, especially in terms of our feedback on the car and what I can learn from him. He's a really nice person and very open on a professional level. It will be a great learning experience."

Knowing Afla Romeo team principal Frederic Vasseur from his F3 days is also helping Zhou transition to F1, and he described their reunion as "unbelievable".

"I will need to keep cooperating with the team, including participating in the coming winter testing sessions," Zhou added.

"I will need to have more discussions with the engineers and team members. We've established a good process, and the engineers are familiar with my driving habits and style."
