Pro's:
-Players become less tired
Con's
- There will be less teams
Other factors
- Would the league become less competitive/less interesting?
Views from Serie A would be of interest as well to see how they feel about the 18 team league there and whether there have been calls to increase the number.
My personal view if that 18 teams would be too few. Teams have adjusted now by not taking the league cup seriously.
The main issue is in interantional comp years but I think through a subtle re-jigging of the fiuxtre list the build-up of fixtures towards the end of the season could be reduced
