Paris Saint Germain sporting director Leonardo says that they are set for talks with AC Milan over Thiago Silva.
Milan have long insisted that Silva, widely regarded as one of the best defenders in the world, is not for sale.
But French reports claim that a deal worth in excess of £40million could be completed this week, making it one of the biggest transfers in history.
"We're going to see Thiago, but it is not easy!" Leonardo is quoted by L'Equipe.
Should the deal happen, it would be a club record for PSG - who are also closing in on a £20million plus deal for Napoli's Ezequiel Lavezzi.
Milan have yet to make a comment, but the player's agent refused to rule out the move.
"For now he is still a Rossoneri player, but anything can happen," Paulo Toninetto told RMC.
"I know that PSG are interested in the player. Let's see what occurs."
