Antonio Giovinazzi says Alfa Romeo needs to “understand better” why its C38 has been unable to fight for the top 10 positions in recent grands prix.
Alfa Romeo has amassed only three points since Formula 1’s summer break, all courtesy of Giovinazzi, and has not taken a top 10 result across the past four events.
It marks the team’s worst run of form since the 2017 season.
Giovinazzi classified 14th at the United States Grand Prix while team-mate Kimi Raikkonen was 12th, before moving up to 11th post-race due to a penalty for Daniil Kvyat.
“I think we are still struggling on race pace,” said Giovinazzi.
“We are trying to do something, but it’s not enough. Trying to do something next week, and try to make it better for Brazil.
“[The car was] a bit too difficult to drive on the race. But, we don’t know, to be honest, how we can try to come out from this saga. We need to work on it and try to find a solution.”
Alfa Romeo’s form through 2019 has come as a contrast to its performance through 2018 – as Sauber – when it rose to lead the midfield through the final grands prix.
“Of course, it’s been a bit more difficult this year,” said Giovinazzi, who will continue to race for Alfa Romeo in 2020.
“The important thing I think is we try to understand better and hopefully we can improve the car for the last two races.
“And then, hopefully, also for the team to try to have a better car for next year.”
