Juventus GM Beppe Marotta says Italy's European participants deserve better scheduling.
Marotta says Italy's busy programme has local clubs at a disadvantage.
"The Italian League is a difficult one that's very balanced," he told reporters. "It's a really tough championship.
"So I think we need to appeal to the authorities for better planning of fixtures in relation to European commitments.
"This is a line of inquiry that we will be pursuing, and we hope to achieve something in the future."
