Liverpool face the threat of being forced to play a Champions League match behind closed doors next season with Uefa to determine on Thursday what punishment the Merseyside club will face over the disgraceful attack on Manchester City’s team bus last month.

City – who hope to wrap up the signings of Leicester forward Riyad Mahrez and Napoli midfielder Jorginho for a combined £102 million early next week – will await the verdict with interest as Uefa’s control, ethics and disciplinary body prepare to rule on the matter in Nyon on Thursday morning.

The Premier League champions have been left exasperated by the lack of information from Merseyside Police over their investigation into the attack, which saw the coach carrying Pep Guardiola and his players to Anfield bombarded with bottles, cans and flares from fans who lined the streets approaching the ground.

Eight weeks have passed since the trouble flared in the lead up to kick off of the first leg of their Champions League quarter-final and Merseyside Police have still to make any arrests, despite continuing to appeal for information, and City are dismayed by the radio silence.

No one inside the City team bus was hurt but the vehicle was declared unfit to drive after the attack in which windows and a door were smashed, forcing the Manchester club to source another coach to take them home. City were being particularly aggrieved at the time that Merseyside Police had publicised the route the bus was taking on social media.
