There is a picture on the wall of the Grealish family home in Birmingham of a teenage Jack in the colours of his country - Republic of Ireland, that is.
Still just 17 and yet to kick a ball for Aston Villa, he was already a starter for Ireland's Under 21s. In Dublin and beyond, word was spreading of the English-born prodigy seemingly so happy in green.
With hindsight, Ireland should have acted then, playing on the lure of international exposure for one so young and stitching his allegiance to their jersey.

Now the Aston Villa star is making his mark in the England team and could play against Ireland when the two sides meet at Wembley on Thursday night
That would have meant a senior debut for a boy only just finding his feet in the men's game, but the temptation was there.
Ireland boss Martin O'Neill made several trips to Notts County, where Grealish was on loan, only to determine he was not physically ready for the senior stage.
It would perhaps be wrong to look back and criticise O'Neill - some in Ireland do - given qualification for Euro 2016 was his priority, and there is debate as to whether the midfielder would have declined the call-up anyway, like he did in the summer of 2015.
But as England's new star prepares to face Ireland for the first time on Thursday evening, some do wonder if a little more cunning was needed in securing the future of such an obvious talent.
Ireland manager Stephen Kenny hinted at as much this week when, having been asked about Grealish, he spoke of 'exceptional' players accelerating through the age ranks 'quicker'.
