Italy coach Antonio Conte would like to see foreign quotas in Serie A.
The World Cup 2014 debacle prompted soul-searching and calls for limits on foreign players in Serie A.
"I consider it fundamental to force teams to have a minimum number of Italian players on the pitch and other nations are going in this direction too.
"B-Teams can be a positive experiment, but only with a limit at 23 years of age. The important thing is to get young players actually playing.
"As things stand, we are fortunate Zaza plays for Sassuolo, because he'd get no room at a big club."
