That was then. This is now my friend. He didn't have to compete with Berbatov and Tevez (even though Tevez seems on his way out) back then; add to that the fact that Macheda is likely to command a starting place in 2 years, so United don't really need him @ present.
We have young strikers, Daud and Imobile. We shouldn't worry for our forwards such we have a lot, His price is around 20 mil, with 20 mil we can fill up LB RB and a good CB. Defense is key of success, when will you understand tha.
