Is this the set-piece World Cup?

The possession football championed by coaches like Pep Guardiola is supposed to produce aesthetically-pleasing goals. Against strong defences and world-class goalkeepers, sometimes you need to go back to basics.

This World Cup has started with a spate of goals off set pieces and penalty kicks, as many teams have struggled to score in the run of play.

Inevitably, superstars Cristiano Ronaldo and Lionel Messi have been part of the story, though on opposite sides.
