The international ace joined Hilal from Ismaili in the winter transfer window on a loan basis, having featured for the Saudi titans three times so far.

Ali won a penalty kick to help his side beat Shabab 2-0 on Monday. After the league match Calderon said: "He's a distinguished player but needs some time to produce his finest displays.

"I'm convinced with his capabilities and his teammates' too," the Argentine tactician added.

Ali, 24, is spending his first spell away from Egypt at Hilal.

He kicked off his professional career at ENPPI before moving to Asyut Petroleum.

The talented striker flourished at Ismaili and was called up to Egypt's squad for the first time in 2010.
