Portsmouth won't be moving for Egypt striker Amr Zaki.
The Sun says Hart has blocked Amr Zaki's move to Portsmouth.
Pompey's chairman Sulaiman Al-Fahim wanted the former Wigan bad-boy, 26, and had agreed a fee for the striker with Egyptian side Zamalek SC.
But Hart fears Zaki's disruptive influence.
Al-Fahim said: "It's not my decision but Amr loves Portsmouth. He calls me and wants to be part of the team."
