Over the past few months, a contributor on the BGG (The Boardgame Geek) has made some super cool files to download for a bunch of Pocket Sports. International teams cards, mini fields, pitches, ice rinks. Team tokens, quick reference sheets and score boards.......it really is a massive effort and all for the community to use. I won't name him here.....you can see who it is under the files name.
I would encourage you to take a look at these....as I said, they are free to download and there are even some expansion rules for some of the games.
