Frenkie de Jong is taking legal action against Barcelona amid offers from Manchester United and Chelsea.
Mundo Deportivo says De Jong is at at war with Barcelona who he feels have started a media smear campaign against him.
Barca want De Jong to take a pay cut but he's refusing to do so, it's been claimed.
But the Dutch ace is incensed over how he's being portrayed in the media, and blames Barca for spreading the rumours.
And his lawyers have contacted AFE, FIFpro and La Liga to complain about Barca's treatment of De Jong, the report adds.
