It wasn't just Arsenal fans left despondent at 2.25pm on New Year's Day.
Up on Merseyside, those with keen hearing may have detected a collective groan coming from Liverpudlians let down by Arsenal's poor decision making, erratic refereeing and the sheer ruthlessness of Man City.
Indeed, Rodri's scuffed winner hurt Arsenal, Liverpool and Chelsea fans alike and for some, was the death knell for any title race in the second half of the season.
It may be that the Spaniard's goal makes all the difference, but if Liverpool can maintain focus, they won't know that until much later in the season.

Maintaining focus has been the message Jurgen Klopp and his coaching staff have been sending out in recent weeks and it's one Liverpool's players will do well to heed.
Speaking before City's win at Arsenal, he said: "Man City is the team to beat but for that you have to be perfect yourself.
"If you are not perfect yourself then you have to hope City is not perfect, so that is already a passive role which I don't like too much.
"But usually, during a season each team has a problematic phase.
"The shorter that phase is, the more likely it is you get a chance to win something and it's like I said, we will see."
The odds might be stacked against them, but Liverpool mustn't get caught up in the emotions fans will feel every time City win or the Reds drop points.
And Liverpool cannot afford to allow themselves to get swept up in the notion that City are luckier than they in their efforts to win the Premier League.
Have Pep Guardiola's men benefitted from good fortune in recent weeks? Absolutely.
But are they a ruthless and experienced side who know exactly what it takes to win a title? You bet.
Because the truth is, good teams are lucky teams. Manchester United all too often enjoyed the rub of the green during the 90s and 00s and two seasons ago it was Man City fans cursing Jurgen's jammy Reds as they swept all before them to lift the title.
It's what good teams do. And Arsenal found out the hard way on Saturday. The Gunners have a habit of imploding and when they did, City were there to take advantage.
And so that leaves Liverpool needing to start making some luck of their own.
Indeed, far too often this season the Reds haven't been ruthless enough when it comes to winning football matches late on.
Brentford, Brighton, Chelsea, Tottenham, Leicester and even City themselves have benefitted from Liverpool's lack of ruthlessness and it's resulted in far too many dropped points from favourable positions.
City simply don't do that as often, and while they do have a deeper squad and much more in the way of resources, the Reds do have the experience.
Let's face facts, Liverpool were never going to dominate the English game with a team as infinitely wealthy as Sheikh Mansour's as rivals, but they can be there and waiting whenever City waver.
And that's why Guardiola will be sending a message of his own to his players.
Never, ever underestimate Liverpool.
Because one thing we know for sure about Klopp's side is that when the odds are stacked against them, they have a habit of rising like a red phoenix from the ashes and ramming the taunts of rival fans down their throats.
Nobody is safe from the 'devil's club', after all.
Guardiola will know that, and while his side have wracked up 11 consecutive Premier League victories, margins have been fine and should they wobble, Liverpool are just the kind of opponent to take advantage.
And so Liverpool will fight on, hoping that a win against Chelsea extends the title race just that little bit further.
It's not over until it's over. Liverpool fans should know that better than anyone.
