Steven Gerrard wants Jon Moss's officiating in Aston Villa's 2-1 defeat to Liverpool to come under scrutiny and says he is pleased the referee is retiring.

The second-placed Reds moved level on points with Manchester City in the Premier League title with a victory at Villa Park on Tuesday.

Douglas Luiz gave Villa an early lead, but Joel Matip equalised three minutes later and Sadio Mane scored a second-half winner.

Villa manager Gerrard was not impressed with the performance of the experienced Moss, who did not brandish a single yellow card.

Moss will retire at the end of the season and Gerrard could be in hot water after stating that he is happy with the 51-year-old's decision to bring his career to an end.

When informed Moss is about to retire, Gerrard said in a post-match news conference: "Is he? Good."

Asked about the performance of Moss on Tuesday, the former England midfielder replied: "No comment, I just hope that it’s looked at. That's all I say. I hope it's looked at.

"Have I gone to talk to Jon Moss? No. I just hope his performance is looked at. I don’t want to be sour, Liverpool scored two goals against us and we need to look at that and I don’t want to cover over any cracks."
