Just because of the lose Liverpool recorded against Nottingham Forest does not mean that they’re been inconsistent this season. It’s okay to lose a match not losing consecutively is not what is acceptable by any club’s management. Liverpool only lost a match in the premier league, it doesn’t mean they’ll lose their match in the champions league as well even if they’re going to be playing against a more superior team than Nottingham Forest in the champions league. Both teams are good and the match is going to be hard to decide at this point. It is better to remain neutral on this type of matches because both team la even have enough experience in the champions league and they won’t take it easy on each other before we get to see who wins the match at the end of the day. I’m looking forward to this match, because of how entertaining I’m envisioning it to be.
I agree, of course that loss was a total mess and everyone in the club and outside the club knows it. I am sure that literally nobody put a bet on Nottingham Forest in that game. The chances that Liverpool would give away those three points were zero, but as you can see only because a club has a small name doesn't mean that they can't play any football at all. Opponents have to be taken seriously and you could see that. But usually an event like this happens once or at maximum twice in a season. It's not going to happen again I believe.
Whatever it is that happened in that game, just like the Liverpool fans, their players may have underestimated Nottingham Forest. Generally, the loss came to Liverpool as a surprise. However, it's not meant to be the foundation of judgement for their game against Ac Milan, I presume the Liverpool team will buckle up and play a better football. I wouldn't want to predict the outcome of such a competitive game, but from the previous performance of both teams it'll appear to end as a draw.
Maybe one of the reasons for Liverpool's defeat is that they wanted to prepare for the Champions League match. The Champions League is more important and Nottingham was an opponent they did not see as strong. They must have thought that they could beat them in any way and underestimated them. But you shouldn't do that. You should take every opponent seriously, both in the league and in the Champions League. This defeat could even cost Liverpool the championship at the end of the year.
