Our former captain is representing United's team at Anfield, as we look to overturn a 3-1 deficit from the first leg at Old Trafford, in a game that raised over £1.3 million for the club's Foundation.
The charity clash kicks off at 15:00 BST and this is Roy's first involvement for the side, with the Irishman set to appear alongside the likes of Jaap Stam, Darren Fletcher, Michael Carrick and Dimitar Berbatov.
The ground was the venue for what turned out to be Keane's final appearance for the club, after so much distinguished service under Sir Alex Ferguson, in September 2005.
