Barcelona will face competition to sign long-term target Arthur, according to sources in Spain and Brazil.
The LaLiga leaders are already in talks with Gremio to sign the midfielder, who was pictured wearing a Barcelona shirt last year.
The Nou Camp outfit are the only club who have produced an offer for the 21-year-old, but AS reports that Inter Milan, PSG and Monaco have shown interest in him. Meanwhile, according to UOL, Real Madrid and Chelsea are keen on him too.
Barca are willing to offer €30m for Arthur, while Gremio are looking for a fee closer to €50m.
