Anyone who ever saw Paul McGrath's display against Italy in the 1994 World Cup will appreciate that the big man is quite an imposing figure. Getting past his substantial frame is no mean feat, as Roberto Baggio found out to his cost that day. Legends are still told of that famous day, when the Republic won out 1-0, thanks to a chip from Ray Houghton and the Zeus-like display from McGrath.
Having handled some of the deadliest forwards in the game, including Alan Shearer and Roberto Baggio, big Paul has no fear of altercation. So it makes perfect sense that he should set his sights on the organisation currently threatening the peace and security of the entire western world (McGrath has since deleted the tweet).
No doubt ISIS have other things on their mind right now, but if they ever fancy taking on the Republic of Ireland (or, indeed, Aston Villa) in some kind of strange, parallel universe football match, they'd better hope that McGrath doesn't come out of retirement. Even with his dodgy knees.
