Hamann says he would have evaluated every other option available before signing the controversial Italian.
He told the Mail on Sunday: "I would have taken Balotelli on the last day of the window, but not before.
"I would have tried to look at every other option which is out there to see if the right player could be found and a deal could be done.
"And then on the last day if you don't get anyone and he (Balotelli) is still keen on coming to the club I would have taken him, but I wouldn't have taken him a week before - that's for sure.
"Having said that I'd rather have him at the club than not have him at all, because I think he can produce moments of magic which can win you games. We just haven't seen that yet."
