These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way.

YMMV: Mike Bassett: England Manager
Harsher in Hindsight: Wirral County are mentioned as being the less successful rivals of Chester City, and despite the efforts of a corrupt chief executive, narrowly survive the 2007—08 season at the expense of Mansfield Town. In real-life, Chester City survived the same season also at the expense of Mansfield Town... only to get relegated the following year, before going out of business altogether in 2010 thanks to the actions of their corrupt owner. If you assume that the series' talent for predicting the future works both ways, then Mike only succeeded in postponing the demise of Wirral County by two years.
Hilarious in Hindsight: The series has a bizarre knack for predicting the future. In England Manager, England progress through the group stages of the 2002 World Cup thanks to a controversial 1-0 win over Argentina, then progress to the semi-finals where they get knocked out by Brazil, who go on to win the World Cup. All of this actually happened (albeit with England's elimination by Brazil occurring in the quarter-finals) in the real 2002 World Cup, which took place a year after the film's release.
Then in Manager, Mansfield Town get relegated from the Football League at the end of the 2007—08 season. Guess what happened in the actual 2007—08 season?
Rufus Smalls in the film was mentioned as being an extremely popular striker whose reputation went down the tubes after he skied a penalty in a penalty shoot-out in the quarter-finals of the European Championships against Portugal. Fast forward to 2004, and David Beckham's reputation takes a major (albeit fairly short lasting) knock when he has a critical penalty against Portugal in the quarter-finals of the European Championships, and kicked it into Row Z.
We find out that Basset lasted one year after the film as England Manager, after failing to qualify for Euro 2004. England failed to qualify for the real life Euro 2008.
