Manchester United and Paris St Germain have been charged by Uefa following Tuesday night's Champions League clash between the clubs at Old Trafford.
United have been charged with throwing objects and blocking stairways, PSG with throwing objects, setting off fireworks, acts of damage and crowd disturbance.
A beer bottle was thrown from the crowd towards PSG's former United winger Angel Di Maria in the second half of the last-16 first leg, with the Argentinian responding by picking it up and seemingly pretending to take a swig from it.
It has been reported that a bottle of water was subsequently thrown Di Maria's way as well, and an item landed at the feet of United full-back Luke Shaw in the first half of the game, which the visitors won 2-0.
The case will be dealt with by the Uefa Control, Ethics and Disciplinary Body on February 28.
