The start of full training at Italy's professional soccer clubs has been postponed from Monday as they continue to wrangle over the government's medical rules for dealing with the coronavirus.

Several clubs had already decided either to continue with individual training or, at the most, divide players into small groups which would respect social distancing measures.

Serie A clubs hope to resume the league, which has been suspended since March 9, on June 13 but have been locked in to-and-fro discussions with the government over how to do so safely.

The main sticking-point is 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 would be sufficient.

"It is obvious that this would not allow us to finish the championship by August because, if there were 2-3 infected in one or two teams, everything would be systematically blocked for a couple of weeks," Cagliari president Tommaso Giulini told Radio Super Sound. 

"Since this has a good chance of happening, it would mean that 80% to 90% of us would not be able to finish by August 2... We are trying, we need less rigidity and within the next few days we will know something more."

The clubs are also opposed to the stipulation that each squad, including coaching and backup staff, undergo a training camp in complete isolation before the league restarts. They said this would create huge logistical problems. 

Udinese's technical director Pierpaolo Marino said that more training time was needed due to the uncertainty. 

"We still don't know if from tomorrow we can train in groups or individually, as the current guidelines are not fully applicable. If the league resumes on June 13, there will be a very high risk of injury," he told state broadcaster Rai. 

Meanwhile, La Liga president Javier Tebas confirmed clubs in the top two divisions will begin training in groups of up to 10 players from Monday.

The return to group training follows a government announcement on Saturday allowing sports teams to return to activity regardless of the status of the lockdown in their own region.

The provinces of Madrid and Barcelona, home to La Liga giants, are still in strict lockdown measures.

"It's very important that all teams are training at the same level and we are grateful that is now the case," said Tebas.

La Liga is aiming to return on June 12, which has been indefinitely suspended since March 12. Tebas previously warned that clubs would lose up to one billion Euros if the season was not allowed to be completed.

But he said he was feeling even more optimistic now after the Bundesliga became the first major European league to resume action this weekend.

"We have worked very hard alongside them in these last few months, exchanging protocols and ideas and I'm very proud of the Bundesliga because it wasn't easy but they were the first and they are an example to follow."
