PSG star Neymar is backing Arthur for success with Barcelona.

Neymar was back at Barca on Sunday ahead of attending a poker tournament and caught up with his former teammates.

Asked about his fellow Brazilian, Neymar said: "He's a great player and I'm sure he will bring a lot to this club."

Arthur joined Barca this summer in a €31m deal with Gremio.

Barca coach Ernesto Valverde is now weighing up when to introduce Arthur to his first team.
