Sergio Perez has a new boss for 2021, having made the switch from Racing Point to Red Bull Racing.
The Mexican driver pairs up with Christian Horner again, having previously driven for Arden International more than a decade ago during Perez' GP2 days.
Horner is a co-founder of Arden, along with his father Garry, and signed Perez to his team in 2009 alongside Edo Mortara.
"With Christian, I've always had a good relationship and it's always very open," Perez told F1's Beyond the Grid podcast. "And even though my career took a different direction, every time we met in the paddock we always have a good chat."
"With Christia, his dad was more running the team, who I also had a good relationship with. I only did one year with Arden. And I remember that was very difficult because I was not strong enough!
"Arden was very famous for that to have a very strong front end. They were running big steering loads and the steering wheel, you have no idea how heavy it was!
"My teammate Mortara looked more like a bodybuilder than a racing driver!
"I was 18 year old, and I struggled so much physically in the races, I was totally destroyed. So it was pretty difficult in that regard. But we just had a good relationship together. And that worked well."
More than a decade on, and Perez is back working with Horner at Red Bull Racing and expecting to challenge at the front of the grid.
Musing about how much they've changed in the intervening years, Perez said, "Well, I think we've changed both a lot. We've spent a lot of time together since since then. I think Christian has developed a lot, you know, he's a great leader for the team."
"His personality is very strong and he's able to deal with it very, very strongly.
"And same with myself, I'm more experienced. I've delivered over the years and we are together in a great point of our careers."
