It does all beg the question - over the years - how many great players who were eligible to have played for the RoI. Loads. 10% of the UK population has at least 1 Irish grandparent; 20% of the English population has Irish ancestry.
The current English first team squad are not that ethnically English.
Tbh I'm not sure what that is. Ireland youth teams - across all sports including gaelic games - have a good portion of kids with diverse heritage and I think its terrific.
I coach young kids in my local gaa club and there has been a huge increase in participation fom kids from eastern europe and kids with middle eastern or african heritage.
its brilliant to see them embrace it and its a wonderful way to integrate kids into a local community. Whether those kids grow up and want to play for Ireland or the country of their parents heritage is something Irish sports organisations will have to deal with in the coming years.
One of the good things the FAI have done in the last few years (possibly the only good thing) is the establishment of national underage leagues. The idea to provide an alternative route to professional senior football other than going to England or Scotland as a 16 year old.
There was a fear it would destroy schoolboy football but if anything I think its benefited it. The "elite" kids are playing against each other every week and so its a more level playing field in the schoolboy leagues - which are still producing talent over the ages of 16.
