In the aftermath of Manchester United's 5-1 dismantling of FC Midtjylland in the Europa League on Thursday night, almost every football fan in the country will be asking: who on earth is Marcus Rashford?
The 18-year-old has previously been included in match-day squads against Leicester City and Watford this season, yet most United supporters will have been unaware of his existence until now.
The debutant, brought into the starting line-up minutes before kick off for the injured Anthony Martial, bagged a brace to help his side secure their place in the last 16, and in the process sent social media into a frenzy of asking just who this 'Rashford lad' was.

Born in Manchester on October 31, 1997, the Englishman started his career at local club Fletcher Moss before signing for United in 2014, playing for the Under-18s ever since and scoring 13 goals last season.
His electric pace, energy, versatility and eye for goal have caught the attention of many, with academy director Nicky Butt once saying: "Marcus is explosive, he's a very talented boy but a good, hard worker as well."

Such praise from a Red Devils legend will no doubt spark a sense of excitement amongst United fans - but history warns to put the champagne on ice.
Cue the ghost of James Wilson - another so-called United 'wonderkind' who was shipped out on loan to Championship side Brighton & Hove Albion earlier this season.
He's only 20-years-old, of course, so it would be unjust to label him a flop at this point, but Wilson has so far failed to live up to his reputation as United's latest golden boy and disappointed fans who once held him in such high regard.
However, given the club's array of injury woes, there is every chance we will be seeing a lot more of Rashford this season with Louis van Gaal in dire need for some extra firepower, especially so in the build-up to this weekend's colossal Premier League clash with Arsenal.
Whether his development over the coming seasons makes him more akin to Wilson or Martial remains to be seen, but what's clear is that if managed and nurtured correctly, United's flamboyant teenager possesses a raw talent that could transpire into a class act at Old Trafford.
