PSG signed Pastore for a record £42 million in the summer and he has scored several goals to help them to the top of the Ligue 1 table.
“I am surprised by his performance because he had a lot of pressure, because of how much he cost”, said Djorkaeff to France Football.
“In addition, he is only young and he came into a team in transition.
“He’s an exceptional player, very elegant.”
