"I am ready to start in any position," U-21 Egyptian international Gaber said.
Ghanem said he will leave Zamalek in the end of the season after he was deeply criticized by fans and analysts following the 4-2 defeat in Tunisia.
His repeated mistakes in positioning, marking and coverage as well as his reckless challenges were all highlighted in the first-leg of the African Champions League clash.
Ghanem was rounded easily in the build-up for the first goal, couldn't clear an easy cross in the second, and committed a silly foul in the box resulted in a third goal from the spot.
It wasn't the first time when Ghanem fails to deliver in big games, with the 3-3 draw in the Cairo derby with Ahli last season still in mind.
Despite enjoying a huge backing from manager Hossam Hassan, Ghanem seems to be out of the picture in Saturday's return leg.
Gaber, who is originally a defending midfielder, was installed in Ghanem's position during Zamalek's latest two friendlies as well as training sessions.
