Valtteri Bottas and Pierre Gasly face a difficult Italian Grand Prix as both serve hefty penalties for power unit changes.
After setting the fastest time in qualifying on Friday and following that up with victory in the sprint race on Saturday, for Sunday's race, the Mercedes driver starts at the back of the grid.
Mercedes opted to take a complete power unit change on Bottas' car going into the weekend to introduce another system into the pool, leading to a raft of penalties.
The Finnish driver will now start from 19th on the grid, rather than 20th, as Pierre Gasly will start from the pit lane.
