The top-tier Italian football league has been suspended since March 9 due to the coronavirus pandemic, which has killed more than 32,000 people in Italy, and hopes to restart in mid-June but is still waiting for government approval.
Spadafora told state broadcaster Rai that he had scheduled a meeting with the heads of the Italian football federation (FIGC) and Serie A league for next week.
“I think that we will have all the data we need to decide if and when the league will resume,” he said.
“May 28 is the day when we will know if the league will resume.”
Serie A clubs voted earlier this month to resume playing on June 13, but the government has since extended its ban on sporting events until June 14.
The main stumbling block has been the government’s insistence that if a player tests positive the whole squad must go into quarantine for 14 days.
The clubs argue that isolating the player involved should be adequate.
The clubs are also opposed to the stipulation that each squad, including coaching and back-up staff, should undergo a training camp in complete isolation before the league restarts.
They say this would create huge logistical problems.
However, Spadafora said that “the situation allows us to bring in rules which are less strict”.
Meanwhile, the FIGC has set a new date of August 20 for Serie A to finish with the possibility of playoffs in the case of another suspension due to the virus.
A meeting of FIGC’s Federal Council stressed Italian football’s desire for the top leagues to return to action.
“The FIGC expressed its desire to restart and complete the national professional competitions by setting the last closing date of the Serie A, B and C competitions to August 20,” the FIGC said in a statement.
The start of next season will be on September 1.
The FIGC, however, called time on its amateur leagues, including women’s competitions up to Serie B.
A decision on the women’s Serie A will be taken “in the coming days”.
Serie A still has 12 rounds of match days to play plus four games postponed from earlier rounds.
Juventus, chasing a ninth successive title, have a one-point lead over Lazio.
