Italy's footballers' union (AIC) on Tuesday slammed the government's decision not to allow a return to training for team sports while easing coronavirus restrictions for individual athletes.
Prime Minister Giuseppe Conte has announced that individual athletes can train from 4 May, but team sports, including football, must wait until at least 18 May.
The AIC said the decision left footballers "perplexed and surprised".
"The idea seems discriminatory, even illogical to let individual sporting disciplines enter training grounds, but not professional footballers and other athletes registered for team disciplines," the AIC, headed by former Italian international Damiano Tommasi, said in a statement.
"The rule also risks aggravating and not containing the risk.
"For professional athletes this phase of training after such a long period of enforced stop is necessary to avoid injuries and be ready to start training in groups from 18 May."
Italy's 20 top-flight clubs have voted unanimously to complete the league season which has been on hold since 9 March, but the final decision will be down to the government.
In France, Prime Minister Edouard Philippe announced Tuesday that professional football, rugby and other sports cannot resume until the end of the summer.
Italian Sports Minister Vincenzo Spadafora defended his government's cautious approach as Italy grapples with a virus which has killed over 27,000 people in the country.
"The prudence we are having concerning football is what still leaves a glimmer of hope of resuming the championship," Spadafora wrote on Facebook.
"The alternative is to do as France did, to say that football stops here.
"Everything will depend on the evolution of the health crisis and our ability between now and 4 May to respect the rules.
"If we think that from 4 May it's all over and we can resume anything without respecting the rules and take a whole series of precautions, we are wrong and we risk finding ourselves in a worse situation than before."
