Krul: Cisse has added quality to Newcastle play
Cisse struck twice in victory over Liverpool on Sunday.
"He's a fantastic striker," Krul told the Evening Chronicle.
"He shows it day in, day out in training, he's a proper goalscorer. If you give him one chance he puts it into the back of the net. He's a typical number 9 for Newcastle.
"I'm really pleased we signed a top-class striker."
