<p>This week I do some basic drills, some shuttling runs on the massive world of statistics in sport. Former accountant Paul McDonald has many hats, but he is now a sports stat specialist, company founder and originator of the expected transfer values algorithm, trying to bring some sense back to crazy world and numbers of football transfers fees.</p><p>He talks me through xG – the expected goals phenomenon that you may have heard thown around, expected Threat and expected Transfer Value.</p><p>Along the way we discuss players as different as Juan Riquelme and Denis Irwin and whether stats will kill football.</p>
