Antonio told the Footballer’s Football Podcast: "Basically - this is not inside information, nobody has told me anything - but what I have heard is what the boys have been talking about on the training ground.
"As the [Liverpool] players come on, Klopp always gives them a big hug and says 'good luck', but when Mo came on he walked in a different direction and was doing his shinpads and stuff like that. Klopp has put his hand out to him and his hand was there for a bit and as Mo stopped doing what he was doing, he just slapped his [Klopp's] hand as a high five.
"Obviously Klopp didn’t like that and he was like, ‘do you want to sit back down?’, basically saying, 'do you want to go on?'. And nobody has told me what Mo said back."
