Show HN: Football11challenge.com -Soccer squad constraints builder and validator

Hi all, a few months ago a friend and I had a fun time solving this interesting soccer related challenge that was trending on twitter: https://twitter.com/Carra23/status/1250066001821130759

We spent the better part of an hour coming up with our own starting 11. After careful deliberation we arrived at our final squad ...only to discover that Kevin de Bruyne played for Chelsea at some point(in our defense his stint at Chelsea was forgettable...). The entire process was extremely entertaining but I was left disaffected by the manual verification process. We had to think of a player then run over to Wikipedia to peruse the list of clubs that they played for. I thought it would be fun to create a web app that:

Lets users define and share arbitrary constraints for a starting 11 Automate verification of a squad given the set of constraints.

Do play around with it and any feedback is welcome. Thanks!
