Celtic face Stjarnan next week in their opening Champions League qualifier of the campaign and, while Moyes sympathises with the Bhoys' grueling schedule, he has warned that the Scottish champions need to hit their peak as soon as possible.
The former Manchester United manager is quoted as saying by STV: "I don't think it's a great situation that they are being asked to start so early in the season but that's down to where Scotland are in the coefficient
"The games have to start early and it's not easy for Celtic but that's the rules.
"You want your team to be at their best coming into the last few months of the season when you're approaching cup finals and league title races.
"But Celtic need to be at their best at the start and they better be ready. It's the same for the other teams and, of course, they'd like more time but they won't get that so they need to be ready."
Three's the magic number
With all respect to Stjarnan, Celtic's biggest test will likely come in the third Champions League qualifier, where they fell short last season (despite also falling short a round earlier).
The difference this term, of course, is that boss Deila has had a full season at Parkhead and has now got his own signings and pre-season preparations in place.
That said, one of Europe's big sides could stand between Celtic and the Champions League group stages and, despite their valiant efforts, the Inter Milan tie in the Europa League proved how tough it can be.
Moyes, then, is absolutely right - although what he's said isn't exactly rocket science.
