Brazilian international and Barcelona midfielder, Arthur has said he is praying that his country man Neymar returns back to the Camp Nou.
Neymar departed Barcelona to join PSG in the summer of 2017 in a world-record €222 million deal.
But there have been persistent rumours that the 26-year-old is unhappy in France and could make a sensational return to Spain.
Neymar has a release clause in his contract that would allow him to leave Paris Saint-Germain for €160 million (£143m/$182m) in 2020, according to as.
He will be 28 in 2020 and has regularly been linked with a return to Camp Nou.
