Raheem Sterling has cast doubt over the Premier League's plan to resume matches next month with many top stars still not back in training.

Sterling has insisted players would require at least a month of full training before they can be pitched back into big-match action – effectively ruling out the hoped-for return date of June 12.

Speaking in an interview with USA women captain Megan Rapinoe on his Youtube channel, Sterling said: "You can't come back in with one and a half or two weeks (of training).

"The national leagues are a separate thing and they will decide separately how they want to proceed. But I think at least 80 per cent will finish the season."

Ceferin hailed the German league and Government for their organisation of the Bundesliga's resumption.

Play in Germany started on Saturday behind closed doors and appears to have been a success.

"We trust Germans, their authorities are very serious... It's not only about football," Ceferin said.

"It's about people being depressed because we are locked down, because there is so much uncertainty, and football brings life to a usual level.

"Football brings positive energy. It's easier to be home if you can watch sports!

"So I think it's a great [example of] cooperation between the German league and the German government. I hope, and think, they will be very successful."

LaLiga will step up its preparations for a return to action, with group training of up to 10 players allowed from Monday.

Spain's top two leagues are hoping to resume on June 12 and this marks a significant moment of progression.
