He believes Dembele could move to PSG and that this could open the door for Neymar to return.
"There are rumours suggesting that PSG might be interested in Dembele and, even though I think Dembele is a great player, I believe this could be a good opportunity for Barcelona to finally bring Neymar back," Rivaldo wrote for Betfair.
"Of course, Barcelona will need to pay some additional money to pull off the deal, but I think this could be a mutually beneficial piece of business for both clubs.
"Dembele could see it as a good move, as he will have the chance to rediscover his best form and become one of PSG's star players.
"He would be back in his native country and could produce solid performances, so I think this move would be interesting for him.
"But, first we must wait to see if the clubs will reach an agreement."
