Restarting football leagues is likely to be a complex affair, with many factors to consider

With football clubs in most countries having resolved player wage cuts and addressed other costs to some degree, attention is now focusing on how to get the leagues restarted. In the top divisions of most European leagues, broadcast rights form the vast majority of revenue for most clubs. While the loss of matchday revenue from playing in empty stadiums will hurt to some degree, this is a much smaller price to pay than not playing at all.

In order to restart effectively, a number of factors will need to be considered. The "quarantine" model for keeping players and all other required personnel isolated, player readiness after long layoffs from team and game-specific training, venues, broadcast schedules and overall timing. A key issue of player contracts that expire on 31 June has already been raised, and while FIFA have stated an intention to automatically extend these contracts, there are doubts about whether these extensions can be legally enforced. 

There are no doubt many logistical issues to be worked through in order to successfuly restart a league, but the sooner this work begins in earnest, the faster leagues will be able to restart once governments give the go-ahead.
