Bournemouth skipper Adam Smith did not hold back after the match, slamming the incident as a disgrace to the sport.
“Totally unacceptable,” Smith said furiously. "I'm in shock that it happened. In this day and age, it shouldn't be happening. I don't know how Ant has played on and come up with those goals. I feel sorry for Ant. He's a little bit down. Something needs to be done. Taking a knee is not having an effect. We'll support him in there and hopefully he'll be okay.
"I wanted him (Semenyo) to react because that's what I would have done. I would have gone straight over there. It shows what type of man he is to not react, even in the moment when it happened to not react, to carry on, then he reported it to the ref. To come up with those goals shows what type of guy he is and what type of character he has. Fair play to Ant.
"It's more angry, to be honest. Shocked. I said to the ref I wanted him (the supporter) removed immediately. He said we have to go through a process and the police will sort it. The Liverpool players were very supportive as well to Antoine and the rest of the team. I think it was handled in the right way, but just so angry.
"We've had discussions with the Premier League [about discriminatory comments] so they've been taking it seriously, but speaking to some of the lads in there, I don't know what else we can do. We've been doing it for a long time now and no one is getting it. I don't know what to say anymore. I just feel sorry for Ant, who has had to take that tonight. The whole country is watching and for that to happen is shocking."
Liverpool manager Slot assured that the club will co-operate in full measure and said: "It's under investigation with the police now. We've made a very clear statement. This day should be about Diogo (Jota) and the tribute, but we have to address this. It's unacceptable. I spoke to him (Semenyo) after the game to say we will do everything to find this person and wherever we can we will try to help. Credit to him, he's very strong mentally, to get such a strong second-half performance after this shows the kind of player he is. Unacceptable in football in general, let alone at Anfield."
