Hamilton, Verstappen and Sainz all slapped with Italian GP engine penalties

Max Verstappen and Lewis Hamilton are among the Formula 1 drivers who will be handed Italian Grand Prix grid penalties.

As at Spa two weeks ago, teams are using Monza as an ideal place to introduce more components into their pools for the rest of the season.

Following the Italian GP, the next stretch of races aren't favourable to grid drops such as Singapore or Japan, meaning Monza is their last chance until the United States at the earliest.

Below is a full list of drivers who will be issued with penalties this weekend - as of the end of Free Practice 1.

Hamilton to back of grid

Following on from damage sustained in his first lap accident at Spa, Hamilton will be sent to the back of the grid for taking a fourth power unit.

Mercedes have fitted a fourth of the following components: Internal Combustion Engine, turbo-charger, MGU-H, and MGU-K.

He's also taken a fourth exhaust system, but eight of these are allowed throughout the season.

Valtteri Bottas and Yuki Tsunoda of Alfa Romeo and AlphaTauri will join Hamilton at the back of the grid following similar exceeding of permitted components.

As for Verstappen, he's got a simple five-place drop for a new ICE - his fifth of the campaign.

Red Bull teammate Sergio Perez is set for a 10 place drop for his own new parts.

Finally, Carlos Sainz Jr is taking a 15 place grid drop - although will not be sent to the back of the grid.

He has a new MGU-K, MGU-H and energy store aboard the Ferrari.

In addition, he's also got a new gearbox, but the resulting 10 place drop is added together with the 15 place one.
