UEFA have moved the Euros to allow leagues to finish before the start of a new season.
With Champions League and Europa League commitments, they will ENSURE they have these will be completed especially after moving a major tournament which generates millions.
Regarding Leagues, I think they will have showdowns in terms of cancellation due to time constraints on the Coronavirus spreading rapidly plus Governments worldwide having issues with non essential activities.
I fear UEFA will ban English clubs for not complying to their rules which will see clubs missing out on millions for the Premiership utter idiotically to finish this season despite Italy, Germany and others being realistic and having the discussion to void their seasons for the big picture of safety.
Realistic Timetable
Void the League - Immediately
Champions League/Europa finished - August 2020
New Season - October 2020 (closed doors potentially)
No Winter Break
African Nations - January 2021
Reduced Cup Replays for cup competitions including Champions League.
Reduced International Friendlies
