Liverpool seem to be having some issues in their team as to player selection, injury troubles and poor fitness level. It is the job of the manager to try to manage this problems and sort out possible solutions and that is what is expected of Klopp now. As much as some devoted Mane fans would want to believe, this has nothing about Sadio Sadio Mane, some players are performing poorly, Klopp really needs to figure out ways to change the current situation of the team.
Many players are injured, it's natural because this football match is very long and when players get injured it requires a long recovery process and can't be fast, but indeed the manager must pay more attention to the players and provide very full support because at least against Brighton in yesterday's match they managed to survive and make the score draw.
It seems that in yesterday's match Liverpool had regained some of the players who were injured before, especially for Thiago of course, so I don't feel Liverpool are short of players due to injury and also it was the first game after the break. But despite Liverpool's poor performance this season, Brighton is not a weak team either, but considering the situation that Brighton has just changed coaches it should make their condition not as good as before. But the fact is that Liverpool are still difficult to beat Brighton, and Brighton themselves can still play well even though they have changed coaches and this case makes Liverpool indeed in a difficult situation.
