The 33-year old Republic of Ireland international has plenty of experience playing against the English powerhouse during his days with the likes of Tottenham, Liverpool and Leeds United and is again looking forward to taking on the Red Devils later this year.
United and the Galaxy have announced a summer friendly which will take place at the Rose Bowl in Pasadena on July 23 and Keane is eagerly anticipating the clash.
"It's always good to get big teams over here like Manchester United and I think it's great," Keane told the Galaxy's official website.
"Certainly for the younger players and the players who have never experienced playing against these top players.
"For me, of course I've played against them for a long, long time and I know a few of the players personally, so I'll certainly look forward to it.
"It will be a good occasion for everybody to bring a team like Manchester United over to LA."
