As always, Wiki is my friend
3 of the Aussie squad have graced the NYS turf. Baily Wright who came on at half time for Sunderland as we drubbed them 5-1 last season, Riley McGree played for Brum when they beat us 1-0 at the end of the 2021 season during our 4 games in 8 days run and Harry Souter turned out for Fleetwood in the 2-2 draw just before Christmas 2019. (Just noticed Wright hasn't played in this WC yet)
I bet all of those appearances are at the forefront of everyone's mind
I'll see what other pearls of wisdom Wiki can teach me later.
Canada's Junior Hoilett has played for various clubs that played at NYS (QPR and Cardiff) but didn't actually get into a game until he did so for Reading in the 4-0 drubbing we gave them at the start of this season.
Ilias Chair of QPR is one of the Morocco squad but hasn't played yet. I know he gave us some trouble at Loftus Road earlier this season but despite him having been at QPR for almost 6 years I can only find him as a non-used sub in games at NYS.
