The Premier League champions were hammered 4-1 in this Champions League tie at Anfield, meaning they have shipped seven goals at home this week after Saturday's 3-0 defeat to Nottingham Forest.
Asked if his players' form has left him shocked, Slot replied: "I think it is a shock for everyone. For the players, for the journalists in here, for me, for everyone. This is a shock and it’s very, very, very unexpected if you look at the quality we have. Is it a lack of confidence? I didn’t see that in the first half.
"Of course, it is hard if after losing 3-0, straight into this game you concede a goal. I saw the mentality these players have shown so many times since I am here, came back in a way you would like to come back, created chances, we kept them in their half – and after another setback by conceding the 2-1, I also saw us creating chances again to score the 2-2. But, in the end of the game, I did see it affected maybe one or two players that we were 3-1 and 4-1 down, that’s true."
Slot was also asked about his position and whether it would be "fair" to be questioned so soon after winning the Premier League title last season.
He continued: "I don’t think it’s important if it is fair or not. But that it’s normal, that I understand. If any manager around the world loses football games, let alone as many as we have lost, it’s quite normal that people have an opinion about that and if that is fair or not fair, that’s for other people to judge. But that it’s normal, I think it is that if you lose so many times that people start talking about that.
"But no, I am not worried – what I mean with that is that my focus is on other things than worrying about my own position."
On if he feels he retains the backing of the board and management, Slot concedes winning would make things easier.
He added, "Yeah, but not in the sense that they tell me every single minute, ‘We support you, we support you, we support you,’ but we talk a lot if we are winning, like last season, and if we are losing.
"Then they are helpful to me, to the team, so yes we do have those conversations but they don’t call me every single minute of the day to tell me that they still trust me. But we do have the normal conversations and in those conversations I feel the trust, but I haven’t spoken to them after this game yet, so let’s see."
