Antonio Giovinazzi must start delivering results or else, former Formula 1 driver JJ Lehto has claimed.

 After his two appearances replacing Pascal Wehrlein in 2017, the Italian got a second chance at the former Sauber team this season following Charles Leclerc's promotion to Ferrari.

So far though he has failed to capitalise with only one Q3 appearance in Baku and is yet to score a point compared to teammate Kimi Raikkonen's 13.

“Kimi is the only one who can bring the results at the moment," Lehto told Finnish media and was quoted by GPBlog.com.

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

And given the competitiveness within the midfield plus the presence of drivers like Mick Schumacher in Ferrari's Academy, the Finn believes Giovinazzi is walking a tightrope.

“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," he concluded.
