How exactly would Premier League footballers fare in five-a-side football?
There are some players, blessed with majestic balance, an immaculate first touch, indefatigable stamina and intrinsic special awareness, who clearly lend themselves to a smaller sided format.
In the Premier League, the likes of Roberto Firmino, Bernardo Silva and Dele Alli all fall into this bracket.
At Manchester United, Paul Pogba, Bruno Fernandes and Juan Mata all possess the right type of skillset for the smaller sided game, but would any of the current crop get in to an all-time Premier League five-a-side team comprising of Red Devils past or present?
Given United are the most successful side of the Premier League era, earning a place as one of the five would be an esteemed honour for anyone selected.
Here at GiveMeSport, we've narrowed down the shortlist and chosen the best outfit from a pool of immensely talented individuals.
In the classic 1-2-1 formation, this line-up would certainly cause havoc in the cages...
Goalkeeper: David de Gea
While question marks continue to loom over David de Gea following his alarming decline, there is no doubt he is a truly mind-boggling stopper on his day.
On a small pitch, with shots being fired at searing speed from just yards away, reflexes and agility are vital, and De Gea has showcased both of those qualities throughout his career.
Quite simply, he is the best in the business as a shot stopper.
You can see it now: De Gea blocking everything with his feet, springing around with the elasticity of a gymnast and pulling off myriad point-blank saves.
Edwin van der Sar was a close contender for this position, but the Spaniard's golden years at Old Trafford warrant his selection over his predecessor.
Defender: Rio Ferdinand
The technical aspect of five-a-side dictates here.
While Rio Ferdinand is unquestionably one of the best defenders in Man United's history, some may argue that his partner-in-crime Nemanja Vidic was actually a superior talent.
But it is Ferdinand's ability in possession of the ball that gets him the nod here.
His distribution into forward areas would offer a solid platform from which to build attacks, and it's not difficult to imagine him on the front foot at the other end.
Meanwhile, his defensive nous and physicality provide the quality of protection De Gea would need to keep the attacking threat to a minimum.
Midfielder: Eric Cantona
The King. Who else?
The enigmatic Eric Cantona may lack a willingness to chip in defensively, but what he does possess is the best first-touch in the business and a level of nonchalance that every great five-a-side team needs.
What's a small-sided game without a touch of stylistic swagger, a cultured headband or an upturned collar?
Brash, lethal and an intricate passer, Cantona's collection of footballing traits made him one of the best to grace the Old Trafford turf, and that skill set would be just as devastating when both pitch dimensions and number of players are reduced.
Just put the Frenchman on the pitch and he'll do the rest.
Midfielder: Wayne Rooney
Wayne Rooney brings both brains and brawns to United's all-star outfit.
Technical attributes reign supreme in five-a-side football, but there is no question that physicality has a major role to play.
The intensity of sprinting is a gruelling test of athleticism, while the regularity at which players are required to lunge into tackles and scrap for possession demands strength and iron-lungs.
In Rooney United have a talent who, in his prime, consistently backed up his technical offering with an unwavering commitment to retrieve possession.
Add in the fact that England's record scorer is capable of striking the ball with ferocity and immaculate precision and what we have is the perfect all-rounder to seamlessly weave between his defensive and attacking responsibilities.
Attacker: Cristiano Ronaldo
Ronaldo's place in the side was never in doubt.
A footballing god amongst men, the veteran attacker would be fascinating to watch in a small-sided fixture.
The hectic and instinctive nature of five-a-side is conducive to individual moments of flamboyance that are seldom seen on an 11-a-side pitch.
However, Ronaldo is one of those players who is able to channel his thirst for trickery on a full sized pitch, so one can only imagine what he's capable of in a smaller format.
Serving as the focal point in attack, demanding the ball into feet before attempting to conjure up a goal scoring opportunity, the Portugal international would be a menacing prospect for any defender.
Sub: Paul Scholes
United's answer to Andres Iniesta is incredibly unfortunate to miss out here.
Football is a simple game when played in the correct way, a notion that rings particularly true in five-a-side.
Few players in the history of the Premier League can boast a level of intelligence akin to Scholes.
In a small-sided game his ability to find minute pockets of space, thread eye-of-the-needle passes and, most importantly, make the right decisions in split-second scenarios would all come to the fore.
The only concern with the playmaking veteran relates to his finishing ability, but the knack of finding the net is an art that changes here.
In small-sided football, the art of finishing is often synonymous with passing, such is the proximity to, and dimensions of, the goal.
For Scholes, the shift in format should bolster his finishing ability when he subs on for Rooney or Cantona.
