Sebastian Vettel has endured a torrid beginning to the 2021 F1 season with his new team Aston Martin, failing to finish the race at Imola after coming home behind his teammate Lance Stroll in 15th at the Bahrain Grand Prix.
The German former world champion struggled in his last two seasons with Ferrari against Charles Leclerc, and was abruptly dropped from the team before the 2020 season had even got underway.
His former teammate Mark Webber, who spent four seasons with Vettel at Red Bull, has said that the driver is struggling for confidence after his difficult stint with Ferrari, according to Marca.
"I think his confidence is incredibly low right now. His stay at Ferrari didn't work out for him. Sport puts men and women to the test sometimes, but in his case it was a very long period of time," he said.
"I think the rules of these cars do not suit Sebastian very well, they are not his type of car. He likes cars with a lot of grip, with a lot of downforce, and he's a very delicate driver, with a lot of feeling with the car.
"Remember Monza in the rain with the Toro Rosso. It was incredible, he left everyone that day. But when there is less grip, with the Pirelli, the cars now give you less confidence and the rules do not suit him."
Webber added that while he did not like to see his former teammate struggling, the reality of F1 demands consistent high quality performances.
"I think the stars have aligned against him. And you can see him getting tired, he put a lot of effort into Ferrari. And I do not like it," he said.
"People think that I enjoy seeing him suffer and no, I'm not happy. I want to see him do well because it is very strange to see him so different from what he was.
"But this is F1, we cannot complain about it and we cannot lament drivers who do not perform."
