Just like we have a filter for region in which a player was born (North African, Scandinavian, etc), it would be cool to have a filter to search for the city region (like West Midlands or Normandia). The information is already there, so I reckon it would be easy to add.
And with that, you could also add that info for the team in which a player plays, so I could search for players born in West Midlands or players playing in West Midlands.
