It's penalties galore at Monza this weekend with almost one half of the field handed grid drops for various power unit element limit infringements.
It's therefore useful to have a general view of today's penalty-shaped starting grid.
McLaren's Stoffel Vandoorne and Force India's Sergio Perez, who should have both started in the top ten this afternoon, were the latest drivers to suffer a demotion this morning.
So as a reminder, here are the drivers who have been demoted for today's race, and their place on the grid.
Fact of the day: only Hamilton and Grosjean - first and last - will start today's race from the position they qualified in!
P10 - Sergio Perez (5-place grid penalty)
P13 - Max Verstappen (20-place grid penalty)
P14 - Nico Hulkenberg (10-place grid penalty)
P15 - Carlos Sainz (10-place grid penalty)
P16 - Daniel Riccairdo (25-place grid penalty)
P17 - Jolyon Palmer (15-place grid penalty)
P18 - Stoffel Vandoorne (25-place gird penalty)
P19 - Fernando Alonso (35-place grid penalty)
