Even Celtic Football Club are showing their support for Conor McGregor ahead of UFC 189

The world has gone mad for Conor McGregor

Or at least it seems that way today. You can hardly turn on a radio or a TV station without discussion of tonight's fight on station's that have never previously embraced MMA. On top of that, thousands of Irish fans have travelled to Las Vegas to get behind McGregor, while we've seen backing for The Notorious coming from rock royalty in the form of U2 And now Celtic Football Club have issued their support for McGregor as he prepares to face Ched mendes in the MGM Grand. https://twitter.com/celticfc/status/619929529239388160 It's not just giant football club's in Scotland backing McGregor, however. Giants of the teen pop music world are also getting behind the Dubliner. https://twitter.com/NiallOfficial/status/619978111916969984 And then some genuine giants of the wrestling/acting/white teeth game. https://twitter.com/TheRock/status/619993494141161472 You didn't really think that Paul McGrath wouldn't have his say, did you?

Best of luck @TheNotoriousMMA #yourtheretotakeover #proudtobeirish
