Sheffield United made an initial bid of two million Sterling Pounds for Zaki's services but Zamalek turned down the offer.

The Egypt striker claimed earlier this week that Sheffield tabled another bid worth three million.

"I'll present Sheffield's new offer to Zamalek board on Saturday and will hand them an official transfer request," Zaki told FilGoal.com on Friday.

The 24-year-old said that Zamalek coach Henri Michel has given him the green light to leave the Cairo side.

Zaki joined Zamalek in the summer from Russian side Lokomotiv Moscow after a short and unsuccessful spell.

He found the net 11 times for Zamalek, including three goals in the Arab Champions League.
