Liverpool have apologised after the Manchester City team coach was pelted by projectiles and damaged as it approached Anfield for Wednesday night's Champions League encounter.

The Merseyside club rerouted the team buses' approach to the stadium amid safety concerns, after warning fans earlier this week that the use of pyrotechnics outside the ground was potentially illegal.

Despite the changes, a multitude of Liverpool supporters lined the streets, and the Man City coach was hit with bottles and fireworks, shattering windows, while red flares were also let off, hampering visibility.

Liverpool's statement read: "The club condemns in the strongest possible terms the scenes which preceded our Champions League quarter-final, which resulted in damage being inflicted on the Manchester City team bus during their arrival at Anfield.

"We apologise unreservedly to Pep Guardiola, his players, staff and officials caught up in the incident.

"The behaviour of a number of individuals was completely unacceptable and the club will cooperate fully with the authorities to identify those responsible. The priority now is to establish the facts and offer Manchester City whatever support is necessary."

Liverpool and Man City are contesting the first leg of the quarter-final tie on Wednesday night, with the return leg at the Etihad Stadium on Tuesday, April 10.
