Slacking on your lunchbreak or just plain curious about how smart you are? Then prove it with our tough as nails sporting quiz. 

Made up of some of the biggest events from throughout the week, as well as a few questions that we simply plucked from the air or arose in conversation in the office, test your mettle against our fiendishly tough sporting quiz. 

Let us know how you got on by tweeting us @NewstalkSport, and, most importantly, don't disappoint Roy Keane - he'll be dispensing the marks at the end of the quiz.
