City have reportedly voiced their worries about a repeat of the incident in the Champions League quarter-final last year when damage worth thousands of pounds was inflicted on their team coach.
Liverpool apologised and paid compensation and last season the match passed off without incident, but after Merseyside Police confirmed they were aware of one social media post urging fans to bring “pyros and pints”, Klopp sought to play down Sunday’s welcome.
“If someone from City is concerned still, it’s our fault,” said the Liverpool manager.
“We all didn’t throw a bottle, but it was one of us. All of us have to make sure that something like that never happens again.
“We will do everything to make sure it doesn’t happen again.”
Klopp pointed to City’s last match at Anfield, 13 months ago, when the visitors’ coach was virtually ignored as it made its way to the ground.
“It’s long ago and since then nothing has happened. I don’t think it was Man City specific,” he added.
“After the punishment we got, we haven’t had a similar situation – the positive outcome of something like this.
“Actually, we used to enjoy that (the coach welcome), when we come in, it’s impressive.
“It’s a nice part of football, but if you overstep the line then it’s not allowed that you do it any more. That’s how it is.”
