No , maybe I didn't explain very well sorry.
Between may and August you have 2 months off and then preseason for 6 weeks.
So call this time ore season so to speak. It's potentially 2 months off. Then if the football resumes in June (fingers crossed) you finish the season second week July domestically. 4 weeks off , 4 weeks pre season and then start season second week SEP everywhere. Players are still well rested and ready to go.
That's if football returns by then.
It would be I imagine agreed when it will resume for next season for everyone. I don't think one country will start ahead of another one.
There isn't a unsync with Europe anyway. We all have an end date of next season so it's just fitting this one in before that which is the conundrum. Spain have a different schedule to England already.
