Sergio Perez admits that he was hoping to perform better at Red Bull and did not expect to find things so difficult when he first joined the team.
Perez has played a key role in Red Bull's recent success, with the team winning the last four Grand Prix including a win for Perez himself in Azerbaijan. Nevertheless, Perez was a little surprised at the time it takes for an experienced driver to adapt to a new team.
"I found the change of team harder than expected," Perez told RacingNews365.com and other select members of the press. "I think the fact that I came to such a different team, in terms of driving a unique car and so on. It was a big change so it took me longer than expected to get up to speed.
"I'm just getting better. Obviously, I hoped for more by now but still the season is very long."
Perez is up against one of the most talented F1 drivers this century in Max Verstappen, who leads the Drivers' Championship, but is trying to focus on executing his performances as best as he can rather than focusing on what his Dutch teammate is doing.
"We all know in this business how good Max is," explained Perez. "He delivers at an extremely high level from FP1.
"But I'm more focused on my side, on trying to get fully comfortable with things, fully up to speed with describing the car and it was just a very different world to what I was used to.
"There are probably teams out there that are similar to others but I went to another extreme. So I think that made it a bit harder.
"But I'm getting there. I think every single weekend, we see good improvement and I see no reason why I cannot get any better in the next five races, for example, to do another step.
I think I'm happy with with my progression so far with my level that I'm delivering at, but obviously it's not enough and I want more than that."
