The Red Devils romped to a 20th league crown last season thanks to the influence of golden boot winner Robin van Persie, but would fail to secure even a Champions League place if a rule change was made.
While Van Persie found the net 26 times in the Premier League last term, Manchester United were only able to muster 20 goals courtesy of English players - 12 of which came from Wayne Rooney.
The winners of the Premier League, in fact, would have been West Ham after the club managed to score 32 times via an English player, with Kevin Nolan and Andy Carroll contributing 17 of those goals between them.
Other English scorers for the Hammers were Mark Noble, Matt Jarvis, Joe Cole, James Tomkins Carlton Cole, with the bulk of the club's 45 league successes made up of players eligible to represent the Three Lions.
West Ham would have pipped Liverpool to the Premier League title by two points as the Reds, despite the sensational form of Luis Suarez, also relying on an English core of players to find the net.
Southampton - like West Ham promoted last season - would have secured third position, with talisman Rickie Lambert ending his first Premier League campaign as the joint-highest English scorer in the division with an impressive 15 strikes.
Making up the final Champions League place is Chelsea, who clinched third place in the regular season, with Frank Lampard making up the majority of the goals the Blues scored through English sources.
The 34-year-old ended the season with 15 Premier League goals - his best return in three years - which played a significant factor in earning the veteran midfielder a contract extension with Chelsea.
Lampard also broke Chelsea's goalscoring record in the closing weeks of the campaign, as the England international surpassed Bobby Tambling to reach 203 strikes for the Blues.
Elsewhere, Tottenham would have finished just ahead of Arsenal - with the north London rivals claiming sixth and seventh, respectively - while Manchester City would have ended way down in 14th position.
Wigan would still have been relegated from the top-flight, but the Latics would have been joined by Newcastle and West Brom, with Queens Park Rangers and Reading both able to survive the drop.
