Paul McGrath led the way on Tuesday morning as the stars gathered to pay tribute to Liam Miller in a match in Cork.
The former Republic of Ireland international, who played for Manchester United and Celtic, passed away earlier this year after a long battle with cancer at the age of just 36.
And a selection of his former team-mates will play in a game between a United select side and a Celtic and Republic of Ireland combined team on Tuesday afternoon.
McGrath posted a snap to his Instagram account to show he was heading to the game.
He jokingly captioned it: 'On the road to Cork with Big Jacks Cap on, robbed it yesterday'.
Roy Keane will manage the United team, while Martin O'Neill will take charge of the Celtic/Republic side.
Rio Ferdinand, Ryan Giggs and Paul Scholes will don the shirts of their former side in the match.
Meanwhile, current Republic manager O'Neill will be able to call on the likes of Robbie Keane, Damien Duff and John Hartson.
The game will kick off at 3pm at Cork GAA's ground Pairc Ui Chaoimh.
Miller, who earned 21 Republic of Ireland caps during his playing career, also played for Sunderland.
He represented Cork club Eire Og as a youngster while playing Gaelic football and hurling before starting his football career.
Tuesday's match will raise money for Miller's family and for charities.
