Some of the Merseyside club's supporters launched bottles and fireworks at City's bus as the Citizens made their way to the stadium, with one of the vehicle's windows being taken completely out.

A visibly shaken Guardiola was asked about what happened in a pre-match interview at the ground once the players were safely in the Anfield dressing room, and he admitted he and his team did not expect that kind of welcome.

"Normally when the police know it is going to happen, they tried to avoid it from happening," he said, according to Daily Express.

"So I did not expect that from the Liverpool side, their people.

"One year ago, something happened in Dortmund so we come here to play football and I don't understand this kind of situation.

"The bus is destroyed but I did not expect a prestigious club like Liverpool doing this kind of thing. It is not Liverpool, it is the people, but hopefully it does not happen again."

Liverpool issued a public apology for the incident, after which City had to find a new bus to escort their squad and staff home following their 3-0 loss.

It is believed that Reds manager Jurgen Klopp also apologised to Guardiola directly after the Spaniard and his players got off the bus.
