Jurgen Klopp has reacted to a bottle-throwing incident during Saturday's Merseyside derby draw with Everton.
The Liverpool boss was targeted by a fan behind the technical area with a plastic bottle in the 71st minute, after the hosts had a goal disallowed by VAR.
Though he wasn't hurt in the situation, the German says that it still could've 'been really dangerous'.
Speaking after the game, Klopp said: 'No I didn't see it. I thought it was a glass bottle, but it was not. I saw it now because it's still at the "crime scene".
'It looked like a glass bottle, that would've been really dangerous. But it wasn't, it was a plastic bottle.'
The incident occurred in the second-half when defender Conor Coady was judged to be offside by the video assistant referee, after he poked home a cross from Neil Maupay.
As well as the bottle-throwing, one home fan ran on the pitch to confront referee Anthony Taylor about the decision. The Football Association are aware of both incidents and will be investigating them.
It was a tense atmosphere throughout Goodison Park as the two sides battled away in the game.
Liverpool came closest to scoring when they struck the woodwork twice in a matter of moments in the first-half, while Everton's best opportunity can be seen as Coady's disallowed goal.
The centre-back was marginally offside when he steered Maupay's cross into the back of the net from inside the six-yard box, which wasn't initially spotted but eventually overturned by VAR.
