Manchester City say they "regret any offence" caused by a number of their supporters singing about the Hillsborough disaster on Saturday.
Pep Guardiola's side emerged victorious at the Etihad as they beat Liverpool 4-1 to condemn Jurgen Klopp's men to their ninth defeat of the Premier League season.
During the game, City's supporters could once more be heard referencing the Hillsborough disaster of April 1989 that eventually claimed the lives of 97 Liverpool supporters.

It follows a trend that has emerged in recent times with City being forced to repeatedly apologise for the actions of some of their fans. The club say they are "disappointed" to hear about the latest incidents and state they will continue to work with Liverpool to end the disgraceful chanting.
A statement read: "Manchester City FC are disappointed to have heard inappropriate chants from home fans during today's game.
"We regret any offence these chants may have caused and will continue to work with supporters groups and officials from both clubs to eradicate hateful chanting from this fixture."
Relations between the two fanbases have become increasingly fraught over the last couple of years. City claimed they banned a number of supporters who were caught on video singing about the Hillsborough deaths after last year's 2-2 draw at the Etihad, while Pep Guardiola apologised after an FA Cup semi final at Wembley that same month.
City fans scrawled graffiti over the concourses of the away end relating to both Hillsborough and the Heysel tragedy during October's 1-0 win for Liverpool at Anfield also.
In December, a 15-year-old City supporter was left with facial injuries after being struck with a bottle loaded with coins that was thrown from the away end during a Carabao Cup fixture.
Both clubs and their elected fan groups City Matters and the LFC Supporters' Board met before that fixture shortly before Christmas in an effort to try and improve relations between the two sets of fanbases.
