WATCH: Spain took advantage of the new kick-off rule in their Euro 2016 opener

First Northern Ireland gave it  a go and now Spain have changed their kick-off tactics as per the new rules.

A brand new set of rule amendments debuted at the ongoing European Championships in France and one of the most striking ones has already been on display in the tournament. On Sunday, Northern Ireland seemed to adopt a strange approach to kick-off in their Group C opener against Poland as Steven Davis knocked the ball backwards to a teammate rather than tip it forward as we've grown accustomed to. It baffled supporters! https://twitter.com/PabsWilson/status/742125226012647424 https://twitter.com/eeotob/status/742034120180662273 https://twitter.com/seangraham26/status/742115226997428224 The new law allows players to pass the ball in any direction rather than solely forwards. As long as the ball moves then the direction no longer matters. And Spain took full advantage on Monday afternoon by passing all the way back to Gerard Pique to get their Group D clash with the Czech Republic started.

What did I just watch in the Spain game? This is not how you kick off? When did the rules change?? pic.twitter.com/C4RSZZ7S4Y

This one-man kick-off will take an awful long time to get used to.
