George Russell is most impressed with Alfa Romeo after&nbsღp;assessing Williams’ main rivals following Formula 1 pre-season testing in Bahrain.

Alfa Romeo completed 422 laps across the three days of testing - joint with AlphaTauri as the most lapඣs completed by a single team.

Kimi Raikkonen enjoyed a strong final day in the car as he completed 166 laps in the C41 on his way to fourth faste🏅st overall on the final day.

Williams was often battling Haas and Alfa Romeo in 2020, however, Russell believes Alfa has taken a s♌tep forward in 2021 and noted Raikkonen's impressive turn of pace on day three in Bahrain.

“Yeah, Kimi looked very, very fas🍨t today, Russell said after day three of pre-season testing in Bahrain. “I have to give him credit, I need to look deeper into the data but I would say at th☂e moment they look like the most surprising team. 

“I can't honestly tell you where I think we are in comparison because I've only been out with the car for an hour and a half and🉐 I've been deep in debriefs until literally half past eight  But on the fa♔ce of things, Kimi looked very very fast today.”

McLaren’s Lando Norrisꦉ believes Mercedes is on the back foot going into the seas💝on after it struggled for mileage, while when on track, the W12 looked tricky to drive.

Russell - who iꦐs a Mercedes junior driver - remains con✨fident Mercedes will turn things around.

“To be honest, no,” Russell added. At the 🎀moment I'm just focused on us. I've not really looked at the g🐻uys at the top. You know, I've asked them how it's going.  But they are Mercedes, They are going to be fine. I am pretty confident about that.”
