Jamie Carragher could not resist taking a pop at fellow pundit Gary Neville as the Premier League title battle between Liverpool and Manchester United gathers pace.
Jurgen Klopp's Reds remain top of the table but old rivals United now only trail them on goal difference after beating Aston Villa 2-1 at Old Trafford on New Year's Day.
Ole Gunnar Solskjaer's men clinched victory courtesy of a Bruno Fernandes penalty - but not everyone agreed with the decision to award the spot kick.
Referee Michael Oliver adjudged that Paul Pogba had been fouled by Douglas Luiz in the area - and that call was not upheld following a VAR review.
Former United defender Neville also thought it was a penalty - and celebrated the win by posting a photograph of himself with a bottle of champagne on Twitter.
The caption read: "Happy New Year (Joint Top)" followed by a laughing emoji.
Former Liverpool defender Carragher responded: "He had the champagne ready! No wonder he said Pogba’s was a pen but Tierney’s wasn’t!!"
Carragher was referring to another controversial penalty award by Oliver during Arsenal's recent 3-1 win over Chelsea.
Neville claimed that Arsenal's Kieran Tierney had "played" Chelsea's Reece James in winning the spot kick.
Liverpool supporters were quick to side with Carragher over what they saw as a case of double standards from Neville - and premature celebrations, albeit tongue-in-cheek.
"They might just nick it if Pogba keeps tripping himself up in the box," one fan said on Twitter.
Another tweeted: "They are 2nd explain to him how league table works Jamie."
