Been recently turning my hand to a little side project - to catalogue each World Cup Finals Fixture ever played - and the full officiating details for each game.
This was inspired by finding out that Concetto Lo Bello refereed at a World Cup Finals (to which I was unaware).
I've started building the site here:
http://worldcup.bafra77.co.uk - and have all the details in for the 1930 Finals.
Clicking on each Official in the match page (where they are highlighted in blue) - will take you through to a profile page - detailing, amongst other things, how many games they did, who played and in what capacity they officiated that fixture.
On each Referee profile page (eg.
http://worldcup.bafra77.co.uk/player/john-langenus/ ) - next to their name is a number.
This is the order in which they refereed their first game (a bit like Test Match Cricketers have on their shirts to denote in which order they debuted for their country - so Langenus was the 8th different referee to referee a World Cup Finals game.
I'll hopefully be able to pull that numbering through to 2018 eventually - which will be interesting to see the results.
