Antonio Giovinazzi needs to up his game.

That is the view of former F1 driver JJ Lehto, who warned that if the Italian driver doesn't improve, he is at risk of being ousted by Alfa Romeo.

"Kimi is the only one who can bring the results at the moment," the Finn told Iltalehti newspaper.

"Giovinazzi looks lost and helpless compared to him. In all the other mid-level teams, they have two drivers who are on the pace," Lehto added.

He thinks Alfa Romeo will eventually have to deal with the issue, even though Giovinazzi is supported by the team's partner Ferrari.

"There will certainly be changes at some point. There's probably a lot of politics in the background, but the fact is that Alfa Romeo needs two drivers capable of bringing in points," Lehto said.

It is notable that Alfa Romeo struggled generally in Barcelona. Earlier, the team was praised for its Ferrari-like front wing concept for the 2019 rules.

Now, Ferrari boss Mattia Binotto is hinting that the "concept" is in fact wrong.

Asked how Barcelona went for Alfa Romeo, boss Frederic Vasseur told Blick newspaper: "The word has four letters, but you're not allowed to print that.

"Now we hope that Kimi and our young driver (Callum) Ilott can work on solving the tyre problem at the testing this week."
