Liverpool have warned travelling supporters not to take flares and smoke bombs into the ground for Tuesday's Champions League quarter-final tie at Manchester City.
UEFA charged Liverpool with four breaches of its disciplinary regulations following last week's first leg at Anfield, which Jurgen Klopp's side won 3-0.
The charges related to incidents before the match, where fans threw bottles, flares and other objects at the City team bus, which was damaged and a replacement had to be sought for the journey home.
UEFA's Control, Ethics and Disciplinary Body will hear the case on May 31 and Liverpool are keen to avoid further scrutiny from European football's governing body.
