Going unbeaten in the league would be a huge achievement though and I hope he doesn't throw that away.
I agree, that's why I doubt Klopp will do any rotations this weekend. They've gotten this far going unbeaten, and with only 13 games left in the season and not much contention in their upcoming schedule, it seems they can easily set the records and take the league without a loss. Klopp can probably taste it. I hope he doesn't sacrifice the CL, but I have a feeling he's looking at making EPL history this year. LFC can do it with many more wins than the Gunners had in 2003-04, we're witnessing the new "Invincibles."
To pass the season without any defeats is a great achievement, but I dont think that it will be seriously considered by anyone in the management of the team, given that the whole fight for the Champions League is ahead. I think the victory in the Champions League will be much more important than the statistical achievements inside domestic championship (which in any case will be won).
The domestic league is also important because Liverpool haven't lifted the EPL trophy for a long time and this season with an unbeaten record Liverpool will win it.
The UCL trophy is also very important where last season Liverpool won it and now they want the torfi again maybe Klop is ready with his consequences to have to face some obstacles the big club will pass on.
