Kranjcar, the father of Tottenham midfielder Nico, has lifted his team to the top of Group G after three 1-0 victories against Wales, Bulgaria and Switzerland.

To equalize the measurement of team performance across eras, we've created the G-score (as in "greatness"), basically a zippy name for what statistical connoisseurs call standard deviation.
