In Egypt, he's a god, and he's given boys and girls there the belief that they can go on and be a professional footballer. That's the sort of person he is."
Rush added: “As a player he can hardly do any more.
“I watch him now, and his overall game is a million times better than when he first came.
“When he came, he was scoring goals for fun. Now he's scoring goals for fun and making them for fun! His assists are just as important as his goals now, which shows how much of an all-round player he has become."
