Barcelona are confident seeing off a late push from Real Madrid to sign Gremio midfielder Arthur Melo.
Barca have been in talks with Arthur and Gremio for some months about a 2018 deal.
Real have joined the battle in recent weeks, encouraged by Gremio's anger over visiting Barca officials being photographed with Arthur and the player also being snapped in a Blaugrana shirt.
However, Don Balon says Barca remain confident Gremio will do business with them ahead of Real.
The Catalans believe their proposal of a €50m deal, with Arthur to be loaned for the first-half of 2018 back to the Brazilians, should smooth any tension between the two clubs.
