Steve Bruce was present at a Zamalek league game towards the end of last season, where Zaki scored twice, and was said to be sufficiently persuaded to pay 6 million pounds for the attacker.
Zaki was hugely impressive in his country’s Africa Cup Of Nations triumph this year, where he was an integral member of the starting XI.
The 25 year old had previously been on the books of Russian giants Lokomotiv Moscow but failed to make a single appearance.
He has however, been hugely impressive for Zamalek since signing in 2006 where he has netted 22 times in 54 appearances. He has also a formidable international scoring record; 21 goals in 40 caps, including two Africa Cup Of Nations semi final goals - in 2006 and 2008.
The deal will be seen as a considerable coup for Bruce and Wigan; Zaki comes with the reputation of being one of the best African strikers still playing on the continent.
It is expected that the deal will be confirmed later this week.
