Hey,
One of the least exciting things I built at a club was a calculator.
When the recruitment team liked a player from abroad, it worked out whether he'd get enough points for a work permit.
He needs 15, and they come from things like his share of league minutes, how strong his league is, whether his club played in Europe and whether he's a regular for his country. Get 15 and the club can sign him. Get 14 and the deal's off.
