Wales are going to their first World Cup in 64 years, and Sunday's game was arguably the biggest moment in Welsh sporting history. So there is bound to be a touch of controversy along the way.
Gareth Bale's free-kick on 33 minutes ignited the flame on a historic night in Cardiff, but since then, whether it was his goal or not has been heavily debated by fans on social media. The goal was given to Andriy Yarmolenko of Ukraine.
Bale drove a trademark dipping free-kick towards Georgiy Bushchan's goal from 30 yards out, before Yarmolenko headed the ball into his own net. The rules suggest that if a deflected shot is already on target, then it may be awarded to the player who shot at goal, in this case, Bale.
