The statement said that the chants came from the section housing the away team's fans.
During the first half of the game, there was a chant of "murderers" and "always the victims." In 1989 there were 97 deaths of supporters of the Reds and in 1985 there were 39 deaths of fans of the Bianconeri.
Rivalry between the two teams has resulted in chants about the tragedies of the past. The two clubs worked together to stop the chanting.
During Sunday's game against City, the chants about Heysel were audible, as well as the fact that they will work with the premier league champion to stamp out future incidents.
Graffiti associated with the disasters was found in the away section of the stadium, according to the club.
The statement said they were disappointed to hear vile chants relating to football stadium tragedies from the away section.

The impact such behavior has on the families and survivors of disasters is well known.
We will work with the authorities and Manchester City in order to eradicate the chants from football altogether.
