Ronaldinho has come out to advice his fellow countryman on his decision telling him to follow his heart.
There have been recent talks on Neymar leaving Camp Nou for a staggering fee but speculation keeps rising without action.
The latest reports in France suggest the Brazil star could finalise a move to the Ligue 1 side as early as Monday of next week after agreeing terms over a world-record €222million transfer.
Ronaldinho also had a stint with PSG before joining Barca in 2003 and went on to win two La Liga titles and the Champions League.
Neymar have been silent on recent issues about his transfer which might indicate he is interested in moving to PSG after reports of him being unsettled in Catalonia.
