Vahid vow threatens United bid
After chairman Francis Graille revealed he had denied United the opportunity to discuss a blockbusting summer transfer for the Brazilian, Halilhodzic claims he will manage to hang onto a player he describes as a "genius".
With several Serie A clubs also casting envious glances towards the forward, it is expected that the former Gremio ace will head for a larger profile club in the summer.
Yet Halilhodzic, who will replace Luis Fernandez at the PSG helm, does not feel this will be the case.
"When I met the Canal+ (PSG's major shareholder) officials and my future chairman, the first thing I asked was if Ronaldinho could stay at Paris next season," he revealed.
"You can trust me. I will do everything to keep him.
"He is a genius.
"I always have the last word about the contracts.
"I decide who leaves and who stays, even if it is (Diego) Maradona or Pele.
"I will have a talk with him. If he will leave, it will mean something has happened and I will tell you what."
