Celtic have hit out at a series of incidents involving Rangers fans during Sunday's clash at Celtic Park.
The Parkhead club have accused away supporters of targeting home fans with missiles as well as directing 'sickening chants' at players.
Celtic were beaten 2-1 by Rangers and the club have expressed their unhappiness with how away fans acted during the game.
Only 800 Rangers supporters were in attendance but the Hoops say there was a number of incidents that they will look to deal with over the coming days and weeks.
Record Sport understands Leigh Griffiths was targeted from the away end by chants about his mental health and several songs were sung about the Celtic Boys Club scandal.
That includes the previously mentioned chants and missile throwing as well as anything else that is reported to them.
A Celtic spokesperson said: "We are aware of a number of incidents from Sunday's match including Celtic supporters being targeted with missiles from the away support, something which has unfortunately happened on numerous occasions previously.
"We are also aware of a number of other unsavoury incidents involving the away support, including sickening chants directed at our players and supporters.
"However, as we always do, Celtic will deal with these and all other incidents responsibly and in a dignified and professional manner and in a way which protects the greater good of the game."
The match ended 2-1 with goals from Ryan Kent and Nikola Katic enough to edge it for Steven Gerrard's men despite Odsonne Edouard's first half equaliser.
