West Ham striker Mauro Zarate has recently been in the news because of transfer speculation over a move to Italy or Spain, but there's also been the small matter of his international allegiance too.
A former Argentina Under-20 international, Zarate has never been capped by Argentina at senior level, and at 27, he's taken a big decision.
Having qualified through his father, Zarate has now chosen to represent Chile, meaning he will be starring alongside the likes of Alexis Sanchez and Arturo Vidal at next summer's Copa America tournament.
Or, perhaps not. The notion of him switching from Argentine to Chilean hasn't been met well by Chile fans, and now Queens Park Rangers striker Eduardo Vargas has moved to slam the decision from coach Jorge Sampaoli.
"The truth is that it is something that does not seem right," said Vargas. "The squad is very good Chilean players and we don't need to nationalise others to come and perform in our place. It is up to the coach, but the players are not happy with it.
"It's not a decision very well received by the dressing room but if the technician decides he is important and brings him to the team, welcome," he added.
That has to be the frostiest welcome in recorded history, and it's clear that already Zarate is on a collision course with his Chile team mates.
Sampaoli wanted to add more attacking players to his side, and sought the help of Zarate - as well as Leicester's previously-Argentine striker Leonardo Ulloa - ahead of their home Copa America campaign.
Yet the resistance from the existing players means that Zarate may be left out of the side in a bid to keep squad harmony in tact.
It's particularly interesting to see two Premier League players in a war of words given that they should be representing the same country, but Vargas's comments suggest that he may be worried about his place in the starting line-up - especially with Zarate in good form.
