The French champions have been linked with a move for the 26-year-old for much of the summer but seemed to be priced out of a transfer due to Financial Fair Play (FFP) restrictions. However, since Madrid boss Carlo Ancelotti confirmed earlier on Friday that the former Benfica man, who has also been strongly linked with Manchester United, has requested to move, the rumours have regained potency.
"There are many clubs interested in Di Maria," Blanc confirmed at a press conference on Thursday. "PSG cannot do what we want. It’s a difficult case."
The Parisian side are also straining to keep hold of young midfielder Adrien Rabiot, whose contract is up at the end of the season. Arsenal appear to lead the chase to sign the 19-year-old and Blanc is concerned that his side may be forced to sell.
"It is possible that Rabiot will leave us, but I cannot tell you the destination," he revealed.
"I think that his entourage are profiting from his contractual situation. Rabiot has a very good offer from PSG but apparently it’s not interesting. It’s a shame.
"I want Rabiot to stay, but the decision is not mine."
PSG travel to face Evian on Friday evening in their third Ligue 1 match of the season and they have been boosted by the confirmation that Thiago Motta will be able to feature after being headbutted in the tunnel last week by Brandao.
Zlatan Ibrahimovic, however, is definitely sidelined, though Blanc indicated that the Swede will not be absent for much longer.
