People seem to think Nations League add more games, but it just feels like it because there are more matches bunched up together with fewer total international breaks throughout the year as clubs don't want as many breaks.
I recently read an opinion piece about how it will be more difficult to attract good quality managers for international teams in the future.
Using the example of the Norwegian manager in 2002 that had 10 games in February, March, April May (two games), August, September, October and November.
Whereas now in 2022 there are 8 games in March, June and September (of course set up this way because of the WC, which we aren't part of).
The point was the back in the day we had more constant matches, the international manager had more time to constantly prepare for the next match and work with the team over time, instead of just in 3 gatherings during the year. That this will be less attractive to good managers, other than those looking for their last gig maybe. That perhaps in the future we'll have to allow for the same manager to manage a team and a country at the same time.
Unless we spread out matches again, which the clubs do not want.
