With the "keep your team in a good shape to protect your trophies from other managers" I think that we can be challanged at any time, that we'll see the teams as usual, so we can't see their condition and, well, the idea is keep a high condition during the non-match periods to assure that if we r faced, we have condition, because the visitor team play in automatic like a bot with a defensive bonus, been not present...
And my guess is that like in the IC the matches will not be scheduled, will start asap in minutes/seconds...
