That’s an entirely separate issue.

When it comes to difficulty, it depends on how good the team in particular is.

If you’re the best team in the competition, the Premier League is easier than the Champions League. The league format means variance doesn’t have as big of an impact and so you’re less likely to fail to win the competition because of a freak result.

If you’re a somewhat weaker team, I’d say the Champions League is actually easier, even though the average quality of opposition is higher, because it’s easier to get a handful of good results against better teams than it is to outperform your level over a 38 game period.

At this point, they should just make it a rule that any player ruled out of an international with an injury is barred from playing their next club game. Would do a lot to solve these sorts of issues.

Ditto for the horror version of this where instead of there being a hot neighbour it’s a weird cranky murderous old guy or the cottage is haunted.

Their squad is actually very small relative to other big clubs and they buy players who are willing to play slightly fewer games in exchange for a guaranteed shot at winning major trophies. They also try to get versatile players so they don’t have to have a bunch of backups rotting on the bench.

Hasn’t Liverpool basically already answered that question? They’ve toned it down a bit recently but they were on a ~18 month cycle of playing super intense football before burning out and accumulating a load of injuries for a while.

I don’t think they’ve hit that point yet but obviously at some point you do have to be able to take the foot off the pedal a bit if you’re playing 2 games a week as the norm.
