The United Legends team, managed and captained by Keane, beat a combined Celtic and Republic of Ireland side on penalties after a 2-2 draw in 90 minutes.
The game took place in front of 45,000 fans at Pairc Ui Chaoimh, a GAA stadium in Cork, Miller’s hometown. The proceeds from the match will be donated to Liam’s wife Clare and several deserving charities.
Miller, who passed away in February at the age of 36, made 22 appearances for United after moving from Celtic in 2004. He also played for Leeds United, Sunderland, Hibernian and earned 21 international caps for the Republic of Ireland.
