I have a different theory, Yusuf Tazim is Malik's descendant 1. If his name if westernized, it is Tazim Yusuf. tazim was the name of Malik's son. 2. he shares a rivalry with ezio, malik shared a rivalry with ezio's ancestor, Altair. 3. he is a master assassin, just like Malik. 4.He is second in command compared to Ezio. malik was Altair's second in command.

just my theory, but It makes sense.
