Can anybody explain to me (because I've only been watching football since 1966 and so don't know all that much about it) how Italy were top of their group until those late goals went in and clarified it all. At the time Italy, Croatia and Spain were all on 5 points, but Italy had scored the least number of goals, had the worst goal difference and hadn't won head to head against either of the other two. . . . . yet they were top of the group, when by my reckoning they hadn't even qualified??
