Manchester United manager Ole Gunnar Solskjaer joined Manchester City counterpart Pep Guardiola in condemning the fan behaviour that marred Wednesday's Manchester derby.
United beat City 1-0 at the Etihad Stadium in the second leg of their Carabao Cup semi-final tie, but the Sky Blues advanced to the final because of their 3-2 aggregate win.
Nemanja Matic scored the only goal of the game in the first half and was also sent off for a second bookable offence in the 76th minute.
The fixture was soured by some home fans making aeroplane gestures—a reference to the 1958 Munich air disaster, the anniversary of which is on February 6—and throwing seats.
