With Neymar finding himself at the centre of a huge transfer wrangle between Barcelona and PSG, it would appear that the Brazil superstar is beginning to lose the support of his once-adoring public.

Reports and counter-reports continue to circulate about Neymar's prospective €222 million summer switch to Paris -- conjecture that is beginning to irritate Barca fans, who simply demand nothing short of unwavering loyalty from their players.

Indeed, a strongly-worded, homemade poster has been spotted on the streets of Barcelona, taped haphazardly to a lamppost.

"Wanted: Traitor," the poster reads, along with a picture of Neymar's face.

"Mercenaries out of Barcelona. Only players who love the shirt."

Looks like things are about to get ugly.
