Why? We've been improving as a team year after year and we'll continue to improve even if we don't sign someone. Saying it's clear we need someone to finish off the chances is wrong. It's not clear, it's your opinion.
That's what Rooney, Ronaldo and Tevez are there for, as well as being very talented players with many more attributes, something Huntelaar lacks. None of them are goalscoring strikers but they are good enough to help us win the league and Champions League double.
It is clear. If you don't see that then it's something you don't see. My point is that we don't need Berbatov as much as people seem to think we do, but assuming we do sign someone we need a goalscorer. Ronaldo is not a striker, Tevez doesn't score enough, Rooney doesn't score enough. There is a deficiency there.
