"I think there's a big variety from Saturday to Sunday performance. I think when you look on Saturday performance, we are certainly behind Ferrari and Aston Martin and sometimes the Alpine as well," said Russell.

"When you look into the Sunday performance, we are probably a little bit closer to Aston Martin, but this weekend will be a good test.

"We would like to think we can jump ahead of Ferrari, can hopefully close that gap to Fernando as he is definitely pretty fast, and try and close the gap to Red Bull."
