4 years,that might not make him any better than he actually is.Dont get me wrong,Amauri is a pretty good player,but i think he's already peaked.Huntelaar would be the better investment as he's got youth on his side,and he can still get better.Spending a large amount of Huntelaar seems more justified than spending it on Amauri.Despite being a pretty good player,Amauri isnt worth his asking price.
