Brazilian midfielder Arthur is “praying” compatriot Neymar returns to the LaLiga giants.
Neymar, 26, has been linked with a return to Barca despite being in just his second season at Paris Saint-Germain.
Arthur, who arrived at Barca from Gremio ahead of this season, revealed he was trying to get Neymar back to Camp Nou.
“Personally, I am doing a lot of work to get him back, but he has his life, he knows what he’s doing and I don’t know how deep those negotiations are, if there are options for him to come or not.
“But he is a personal friend and a professional that I admire a lot and would be very happy if he could come back here.”
Neymar has scored 11 goals in 12 Ligue 1 games this season, helping PSG go 13 points clear at the top.
