Midfielder Ralf does want to join Fiorentina, but his agent warns Corinthians are making this “a very difficult negotiation process.”
The 28-year-old Brazilian reportedly extended his contract two weeks ago, but there is a dispute over this.
“There was no renewal. He still has an agreement until 2014,” agent Andrea Costa told Radio Blu.
“We received a proposal from Fiorentina, but the move is not yet on the right track because Corinthians want him to stay until at least after the Club World Cup.
“He would be happy to come to Europe, but the intentions of the Brazilian club are clear and the situation has become difficult. The Viola might have to wait until January.
“Fiorentina are making an enormous effort, but this is a very difficult negotiation process.”
