Few suggestions off the top of my head:
Chinese Super League players
Players never to have played in a major international tournament
Bearing in mind there’s 24 people picking, I’m not sure I can even name 24 Canadian players, we may all just end up with an unwanted dud if we do that. I was thinking of maybe suggesting North Americans yesterday but even that felt like it would be a struggle once we got past halfway especially considering goalkeepers is having its own separate category.
