Hugo Ekitike and Cody Gakpo fired Liverpool 2-0 ahead before Antoine Semenyo, after reporting racial abuse coming from a home fan in the first-half, struck twice. However, two late goals from Mohamed Salah and Fede Chiesa saw the Reds win on Friday night.
Slot later said of the game: "If you have half an hour (I can explain how I feel)! But the main emotion should be how impressive and powerful the tribute for Diogo was. The banner the Kop showed, the way You'll Never Walk Alone was sung, the way they sung for Diogo before the game, in the first minute, after 20 minutes and at the end of the game.
"It was all so, so impressive and so powerful and that is, I think, what my main emotion is after the game. Then, there was even a game that ended in 4-2 where a lot of things happened.
"Great game, three teams involved in a great game. You'll ask me why three. Of course, Bournemouth and us playing full gas for 96 minutes or even longer, 99 I think, and the referee that just kept the game going and didn't blow his whistle every single time for every small thing. I think it was a great game to watch. In the end we won it, so that helps for my emotions, but I think this is what you would like to see.
"I have said many times last season about our Paris Saint-Germain game and we can't compare a last-16 game with a first game of football (of the season) in the Premier League in terms of importance, but it was similar. Both teams, all in, high intensity, never gave up both teams and then get a game like this, with a good referee by the way."
I spoke to Semenyo
On the Semenyo abuse, Slot also said: "I think it is under investigation with the police now and the club made a very clear statement about what we feel about this. Unfortunately, we definitely have to talk about this, it's a good thing you talk about this and it's a good thing that I have to answer this, but after actually this day should be about Diogo and about how the tribute was.
"But we definitely need to address this because it's unacceptable in every football stadium, let alone at Anfield. I spoke to him (Semenyo) after the game that we will try to do everything to find that person. I am not 100 per cent sure but I think they already found him. That's a good thing.
"Wherever we can help him we will try to do so. Big credit to him, if something happens like this and you can perform so well in the second half then he's not only a great player, because that I can see (with) how fast he is, but he is also very strong mentally. If something like that happened (and) to get such a second-half performance, that sums up him as a person and him as a player. But, again, (it's) unacceptable in football in general, let alone at Anfield."
