Check results vs federation websites #9

If anyone would like to help with the historic accuracy of the dataset, which would be much appreciated, here's a way to do it:

  1. Find a country that you like
  2. Hope that their football association website keeps good records online
  3. Check this database against theirs
  4. Find the differences - this may be extra matches in either of the database, different results, different match locations
  5. Post the differences here or in a pull request
  6. Peace ✌

Note: Any difference doesn't automatically mean the 'official' source is correct. They might count things like Olympic Games results, results against select or B-teams. On the other hand, they might not count matches that took place outside the specific FA's jurisdiction: for example, Argentina had, for a while, two Football Federations. The one that won out, doesn't count the other's results, I do. Or the England FA took longer to restart after WW2 than the England football team so there are a bunch of matches they don't count.

Checked teams so far:

Something to consider - there may be pre-Olympic friendlies in the database, which will have to be removed. Some official sources might count those are full internationals too.
