Just to have an idea about the changes:
Of the 15 LMS LMP2 runners currently at Monza
5 would be good-to-go under 2021 regulations:
* #25 Algarve Pro: Falb (B) - Trummer (G) - Aubry (G)
* #27 Dragonspeed: Hedman (B) - Hanley (G) - Milesi (S)
* #34 Inter Europol: Smiechowski (S) - Binder (S) - Isaakyan (G)
* #37 Cool: Lapierre (P) - Borga (S) - Coigny (B)
* #50 Richard Mille: Calderon (S) - Floersch (S) - Visser (S)
3 would be OK if they add an extra driver:
* #20 High Class: Fjordbach (S) - Andersen (B) -> can add any category
* #22 United: Hanson (S) - Albuquerque (P) -> needs a silver or bronze
* #35 BHK: Dracone (S) - Campana (G) -> needs a silver or bronze
7 would have to change at least one driver:
* #24 Algarve Pro: Enqvist (S) - Lancaster (G) - Maini (G)
* #26 G-Drive: Rusinov (G) - Jensen (S) - Vergne (P)
* #28 IDEC: Lafargue (S) - Chatin (G) - Bradley (G)
* #30 Duqueine: Gommendy (P) - Hirschi (G) - Tereschenko (S)
* #31 Panis: Canal (S) - Jamin (G) - Stevens (P)
* #32 United: Owen (S) - Brundle (G) - Van Uitert (G)
* #39 Graff: Allen (G) - Laurent (G) - Cougnaud (S)

This now disappeared entry would also be outlawed:
#21 Dragonspeed: Rojas (G) - Hanley (G) - Buret (S)
