Only the most driven and devoted will get full marks in our Roy Keane quiz
Put down the prawn sandwiches and get stuck into this
We have the ultimate Roy Keane quiz that covers his playing days and all the many highs and well-publicised lows that came with it.
Even Keane himself would likely find this one difficult, so you'll have to be a die-hard fan to get all 20 questions right. We reckon anything over 15 is a truly great effort.
