One of the joys of football is that each match presents the opportunity for something to happen that's never been seen before.
Take Saturday's goal by Celta de Vigo midfielder Pablo Hernández, for example.
In what can only be described as a goal that would have Zlatan Ibrahimovic grinning, Hernández opened the scoring against reigning La Liga champions Atletico Madrid by tracking down a long ball into the 18-yard box and somehow popping it past 'keeper Moyá with a back-heel volley while facing away from the net.
Absolutely stunning.
