It is not too difficult for Liverpool to beat Southampton who are currently languishing at the bottom of the standings, but Arne Slot will not take any risks in this game because he must keep his core players fit to face PSG in the second leg of the UCL. Rotation will be carried out in several positions to prevent their mainstay players from getting tired or in the worst case scenario getting injured, but Liverpool must still prioritize their goal of getting three points to prevent Arsenal from closing the gap on them.
The best situation is trying to do some rotation of players to maintain fitness in preparation for facing PSG in the second leg. But if the rotation is not done properly, it will slightly affect the pattern of the game and it is possible that it will end in a draw or defeat. The Premier League is different because even though the team is at the bottom of the standings, if there is a small mistake they can punish the top team.
Arne Slot must be careful if he wants to rotate because after all, victory is something they must get in even easy matches because unexpected results can happen if Arne Slot makes the wrong rotation of players for the remaining matches ahead.
