It's never been done by a Premier League club.
But winning four tournaments is not impossible as Celtic proved in their annus mirabilis, 1966-67, when Jock Stein's team claimed five illustrious pieces of silverware.
More recently, Real Madrid mopped up La Liga, the Champions League, UEFA Super Cup and FIFA Club World Cup in 2016-17.
Manchester City have put themselves in a position to create history this season by winning four competitions.
With just six games left to be played in the Premier League, Pep Guardiola's side are approaching what Alex Ferguson once memorable termed "squeaky bum time."
The League Cup, confirmed by a penalty shoot-out win against Chelsea in February, is already in the bag.
That leaves Manchester City with three more trophies to collect if they're to improve on the three won by neighbours Man United in 1999 and Liverpool's impressive treble in 1984.
Pep Guardiola has the roadmap and City know what they have to do to reach their destination.
It's a gruelling schedule that, starting with tomorrow's FA Cup semi-final against Brighton at the Ethiad Stadium, requires four big performances over twelve days.
Indeed, with vital matches coming thick and fast, this month will provide a stern test of endurance, resilience and determination.
The squad appear to have the right mindset.
Before their 2-0 win against Cardiff City on Wednesday night took City back to the top of the league, Bernardo Silva insisted: "We are not thinking about the quadruple right now. We are thinking game by game.
" Game by game, we'll try to win all of our games. You always think, are we able to win it all? But it's not easy."
Having a one-point lead going into the last six games in their league title defence is a good place to be for Guardiola's side.
While the manager has declared, "The Premier League, more than the Champions League, more than FA Cup, more than League Cup, is enough argument to stay focused", there's a sense that Champions League glory would be even more prized by the club.
Lifting La Orejona (the Cup with Big Ears) would confirm what many have long argued, that this City side is one of the best ever teams to come out of England.
It's too early to say if the Blues have over-reached themselves.
As they romped home early in the Premier League last season, City found their Champions League aspirations thwarted by Liverpool.
This season, Liverpool present the challenge in a League run-in that's as thrilling as the car scene in Rebel Without a Cause when, competing against each other in a test of nerve, Corey Allen tells James Dean: "We both head for the edge and the first man who jumps is the chicken."
Someone has to lose. On paper, Liverpool may seem to have the more favourable matches.
Be it to ensure survival or to strive for a top-four place, the teams City face have plenty to play for. And, having beaten City this season, Leicester also have the ability to cause problems.
Four of City's six remaining league matches will be away, including a visit to Old Trafford and a team officially under new management, that of Ole Gunnar Solskjaer, on April 24.
City will be sick of the sight of Spurs over the next few weeks.
On Tuesday, the Blues play Spurs at the London club's new stadium in the first leg of their Champions League quarter-final tie.
The following week, they host Mauricio Pochettino's side in the second leg on Wednesday and again three days later in the league. And that's just four days before a trip to Old Trafford.
Pep Guardiola will have warned his players about the workload required if they're to make football history.
With the quadruple in sight, he says: "I think they are ready."
Either Watford or Wolves await in the FA Cup final if City beat Brighton.
And if they get past Spurs, it'll be either Ajax or Juventus in the Champions League semi-final.
"Every game will be so tough," Pep warned. "We will suffer. But let's see if we can do it. We are going to try. It's still in our hands. We win all the games, we will be champions."
