Roy keane is one of the dirtiest players ever and this video is a good example.
Roy keane was injured by Harrlannd in a Man United Vs Man City game. Harrland screamed to him while he was on the floor to get up and keep playing.
6 months later, in the same game, Roy keane did this and broke harrlands knee. The guy had to retire.
Keane said " now you get up"
just a nice story about Roy Keane
