Diego Costa's controversial decision to turn his back on Brazil and commit his international football eligibility to Spain will be a story we hear a lot about in 2014.
The fact he will travel to his country of birth in the summer donning the shirt of another country makes it a brave choice, but one he hopes will pay off.
Costa was able to apply to FIFA to play for Spain under residency rules, having played in La Liga since 2007.
On Tuesday night in the Copa del Rey he was subject to a new phenomenon, being subjected to a xenophobic barrage of abuse - from fans of away side Valencia.
'Costa, b*****d; you are not Spanish! Costa, b*****d; you are not Spanish! Costa, b*****d; you are not Spanish!' - Is the supposed chants which were directed towards him.
It's difficult to know what to make of it, whether the fans represented a minority of Spanish society unhappy at his decision and the policy of the Spanish FA, or simply the tribal nature of football fans - doing anything they could to upset and distract the opposing player.
Costa, a transfer target for both Arsenal and Chelsea, has been speaking about the incident to newspaper El Confidencial.
"The only way to change it is to be playing and scoring a goal with Spain.
"It did not look good, but I do not care, if I am lucky enough to play with Spain and for me ... things are going well. Those who cry to me today, after I applaud."
Costa is right to brush it off, because the last thing he can do is allow it to affect his terrific scoring run heading into 2014.
More than ever he needs to keep his form to guarantee his place in the squad, and then he can begin winning fans over.
There may always be those who will remain unhappy and express their displeasure with the decision, and there could be copycat taunting from rival clubs - but they will be doing Diego Costa a favour.
All it will do is give him a taste of what life in Brazil will be like when he steps onto the pitch in the summer, and that's something he may really want to prepare for.
