Antonelli can thrill his home fans from the back of the grid at Monza

Kimi Antonelli is set for a momentous Monza weekend even if he will be starting his home Italian Grand Prix at the back of the grid and chasing Ferrari.

The Mercedes driver, who turned 20 only last week, arrives as the first Italian in 73 years to lead the Formula One championship to the “Temple of Speed”.

On course to become his country’s first champion since Alberto Ascari secured his second title in 1953, Antonelli leads teammate George Russell and Ferrari’s Lewis Hamilton by 59 points after 12 rounds.

McLaren’s reigning champion Lando Norris is a further 24 points adrift after winning the last two races in Hungary and the Netherlands.

Russell, Hamilton and Norris will all be sensing an opportunity, as will Ferrari’s Charles Leclerc, with Antonelli taking a new engine and with it enough penalties to send him to the back of the field and ensure he will be the chaser and not the chased.

“It’s disappointing for him and for the fans who want to see him fighting from the front in his home race, but our sport doesn’t reward sentiment,” said team boss Toto Wolff.

“When you make decisions that benefit the championship campaign, sometimes you pay a short-term price. The objective now is straightforward: recover as many places as possible and maximise the points.”

Overtaking is always possible at the superfast low-drag circuit with its long straights and slow chicanes, but drivers will have a new challenge with the new power units in managing power deployment given the relative lack of braking zones to recover energy.

That could also mean the use of tactical aerodynamic tows between drivers.

The race, with the fans creating a sea of red beneath the podium, is always special for Ferrari, who also have an updated power unit to boost their hopes of a home win. The team are commemorating the 30th anniversary of Michael Schumacher’s first Italian Grand Prix victory with the team in 1996.

Leclerc has won twice for Ferrari in the past at Monza, Hamilton five times with McLaren and Mercedes.

“Racing in front of our tifosi gives the whole team incredible energy and this year there will be an additional dimension as we celebrate Michael Schumacher and the legacy he has left in our company,” said team boss Fred Vasseur.

McLaren will have some minor aerodynamic upgrades as well as a rotating rear wing — dubbed the “H Wing” — that they tested in practice in Hungary last July without using in the race.

“We know we have had a quick car at the last few races, but we are not taking anything for granted. This is a very different track from the most recent ones, and we can expect a pecking order that not necessarily reflects what has been seen in Hungary and in the Netherlands,” said technical director Neil Houldey.
