The Football Association has expressed concerns over the rise of "abhorrent chants" related to the Hillsborough disaster.
"These chants are highly offensive and deeply upsetting," said the FA.
"We strongly condemn this behaviour. We support clubs and fans who try to stamp out this behaviour from our game."
MP Ian Byrne, himself a survivor of the 1989 tragedy, called on the Premier League to take action against "obscene" Hillsborough chants during football matches in a letter on Monday.
Writing to the league's chief executive Richard Masters, the Liverpool West Derby MP said: "I cannot stress the detrimental impact these chants are having on the families of the 97, the survivors and their families.
