Completing a staggering €222 million move to Paris Saint-Germain in 2017, Neymar left the Spanish giants in an ugly manner, as his departure enraged the Barcelona faithful.
Stoichkov, who spent seven years with the Catalan giants insists the Brazilian playmaker's return to the club might lead to a division in the locker room because other valuable players have been offended in the transfer process of the wantaway forward.
"He would be a bomb inside the locker room," Stoichkov told Univision. "Barcelona don't need Neymar. He would have no space to play because they already have very important players.
"There are [Ousmane] Dembele, [Antoine] Griezmann, [Luis] Suarez, [Lionel] Messi. Where would he play? For my part, I don't want him to come back.
"I'm sure there are players who want to come back and ask the president for his effort, but Barca isn't going to move a single Euro to get him back. Barca doesn't have the money to pay PSG.
"There are [swap] options, but the players Barca is offering to PSG is disrespectful [to the players]. Firstly, because Ivan Rakitic is a great worker, a very humble lad who has never let his guard down and has always defenders the interests of Barcelona.
"And [Philippe] Coutinho cost a lot of money, but he has a lot of ability and I defend him, and hopefully no Barca player leaves."
Having enjoyed a successful two-year spell at the Parc de Princes, Neymar’s future at PSG has hit the rocks as the club’s ultras aimed offensive songs to the 27-year-old in their Ligue 1 opener, though the former Santos winger was not in action for the side.
