A former Ferrari driver has taken aim at Lewis Hamilton after a difficult start to life at the racing team.
The 40-year-old has yet to score a podium in red at the halfway point of the season.
The only success he has achieved is a sprint pole and a win during the Chinese Grand Prix all the way back in March.

Former Ferrari driver Ivan Capelli, who drove for the Scuderia in 1991, believes the seven-time world champion has lost his enthusiasm for the sport, saying: "He can no longer do it."
Capelli explained: "I saw him lose the smile in his eyes. What was his strength, which was to take the team by the hand in difficult moments, he can no longer do it and he has now realised it.
"Especially with such a fast teammate next to him.
"He is living a sort of double life. Away from the tracks, he is the usual Hamilton, the seven-time world champion we know, but once in the car, he can't find an answer to his driving problems."

Capelli is expecting Hamilton to have a much better second half of the season as the seven-time champion will find his form.
"Lewis can still give something to Ferrari," added Capelli.
"To think that he will close the year like this is inconceivable. It's not easy at all.
"Lewis is now aware that he can't adapt to the SF-25 and even the working methods at Ferrari are probably far from what he was used to in 12 years at Mercedes.
"At this point, the only wild card that Hamilton can still play for is 2026: a totally new car, with new rules and where everyone starts on an equal footing."

The new regulations come into effect in 2026 and will see a massive change in the pecking order as the entire car will be redesigned from the ground up.
Hamilton has been enjoying his summer break as he has been posting images on social media showing how he is spending time with his friends and family.
But Martin Brundle has revealed that Hamilton could call time on his career before the end of his Ferrari contract.
The Sky Sports pundit claimed: "The summer break couldn't be more timely for Lewis to have a reset. It's painful to observe this great champion in so much strife.

"We have to expect that he can weather the storm and return to form given his talent and experience, but otherwise, I simply can't see him enduring two more seasons at Ferrari, or anywhere else, like this."
Hamilton has remained defiant when it comes to claims of retirement.
He took to social media on Monday, saying: "I’m always so grateful for this time, for the opportunity to rest and recharge.
"There’s a lot I’ve been meditating on. Every one of us is up against so much, both individually and globally.
"It’s so important that we embrace the light of truth and love and take care of ourselves so that we can better take care of others.
"We can’t look away. We have to keep going, even when it’s difficult."
The seven-time world champion will be looking for a better weekend this weekend when F1 returns to Zandvoort for the penultimate Dutch Grand Prix.
The Ferrari driver has gone well in the Netherlands in the past and will be looking to get his first podium in red this weekend.
