Serie A have announced that clubs can no longer have outfield jerseys that are primarily green from the 2022/23 season.
Although the rule is not valid until next season, league officials opted for an earlier statement which allows clubs time to alter future designs.
It’s understood this change was primarily dictated by television companies, who worry the green kits are too similar to the colour of the pitch and could lead to players blending into the background.
This could prove problematic for Sassuolo in particular, whose first choice kits are green and black stripes.
Atalanta and Lazio also boasted green away kits last term.
The rule changes on kits also affect socks and shorts, so if more than three colours are used, one must be clearly dominant across the jersey, shorts and socks.
