Manchester City have been fined £15,573 by Uefa for incidents in the home leg of their Champions League last-16 tie with Monaco on 21 February.
Europe's governing body said the fine related to a pitch invasion, objects being thrown and a late kick-off.
City won the match 5-3 at Etihad Stadium but lost the return 3-1 and went out on the away goals rule.
Meanwhile, City have accepted a Football Association charge relating to Sunday's league game with Liverpool.
They were charged with failing to "ensure their players conducted themselves in an orderly fashion".
