The deal has been the subject of speculation in recent days.
“An exchange between Pastore and Sneijder? No, we’ll keep Wesley, as he is the best out there,” Moratti told Sky Sport Italia.
“There has already been too much talk about Sneijder. The problem is in the media more than anything else and I have an excellent rapport with the lad.
“When he returns to the disposal of Andrea Stramaccioni, he will be an added bonus for the squad.”
