The Irishman does not think Grealish will be representing the Republic of Ireland in the future.
That decision was criticised heavily by former Birmingham City and Ireland captain Kenny Cunningham yesterday.His father and agent Kevin Grealish then came out and supported him.
Brady, who Grealish has been compared to since his emergence, is an Arsenal legend who also had a mercurial style of play similar to Grealish's.
Brady told RTE Sport, as quoted by the Irish Examiner:
“They’ve been trying to talk the lad. I know this because I know the people that work at youth level.
“They’ve been trying to talk him round to playing for England in the last few years but he’s decided that he wants to play for us. I had hoped that would continue on.
“I fear the fact that he’s dwelling so long means that we may not get him."
Brady played 72 times for the Republic of Ireland in his career and also featured for Arsenal over 250 times before joining Juventus. He is clearly pessimistic about the potential for Grealish to play for Ireland in the future.
Jack Grealish has made a real impact at Aston Villa since Tim Sherwood took over the managerial reigns at Villa Park.
The 19-year-old has gone from hot prospect to first-team regular, which has seen his international future cast into considerable doubt.
The teenager has played for the Republic of Ireland at youth level but is also eligible for England. He has so far failed to commit his future to any nation on the full senior level, preferring to focus on his fledgling club career.
