Mercedes chief sends clear warning to George Russell and Kimi Antonelli ahead of F1 return

Mercedes deputy technical director Simone Resta has issued a warning to George Russell and Kimi Antonelli about their chances of winning the F1 world championship.

At the halfway point of a thrilling F1 campaign, Mercedes have established a lead at the top of the constructors' championship, largely thanks to Antonelli's incredible form.

The 19-year-old has won six of the 11 Grands Prix, including nine podiums, with the teenager recording a third-place finish at the Hungarian Grand Prix last time out.

Despite leading throughout the opening months of the season, Mercedes' dominant streak did come to an end before the summer shutdown, with five different drivers tasting victory in the races leading up to the August break.

Lewis Hamilton is enjoying a strong resurgence with Ferrari, and he's currently 50 points behind Antonelli in the race for the drivers' championship as he aims to win his eighth world title.

Ferrari have also closed the gap to 72 points behind Mercedes in the constructors' table, setting up a potentially thrilling second half of the season.

The seven-time world champion is the most likely to threaten Antonelli's dominance, and Mercedes deputy technical director Simone Resta has warned their drivers that they will face more "intense battles" once the action resumes in Zandvoort on August 23.

"History tells us that the championship always changes after the summer shutdown," Resta told Mercedes' Nu Silver Arrows Radio Show.

"The pressure increases on the teams that are leading, but equally it increases on the teams trying to catch up. The environment becomes more intense, and every result carries more weight. That's when you really see the strength and resilience of an organisation.

"It's where teams demonstrate whether they can handle the pressure and continue performing when the stakes become higher. I'm very interested to see that phase of the season unfold because it's often where championships are ultimately won or lost."

Mercedes have let a healthy advantage at the top slip in recent weeks, with reliability woes and a convergence in race pace allowing the chasing pack to close in.

But Resta is doing his best to keep the team grounded, as there is a long way to go before they can think about winning their ninth constructors' championship.

Kimi Antonelli backed to become like George Russell

Antonelli's mesmeric performances across the F1 campaign have featured an aggressive style, and this fearlessness has played a huge part in his dominance.

Teammate Russell, on the other hand - currently 59 points behind the Italian - has been calmer rather than aggressive with his displays.

According to former F1 driver Thierry Boutsen, Antonelli's approach is no different from how Russell drove at the start of his career.

"I think if you take George from his first F1 season, he would have been as aggressive as Kimi," Boutsen said.

"But he’s learned a lot, he’s calmed down also, he’s got more maturity. He races a totally different way. I believe that Kimi will be the same in three, four years. He will drive very differently to today."

Antonelli has been tipped to adapt his style as he gets older, but right now, his assertiveness and bravery on the track has held the key to a stunning campaign so far.
