It's not really a huge surprise is it, given that most teams spend the bulk of their budgets on centre forwards, whereas we seem to have had an obsession with CBs and wide players over the last decade.
We have seen what can happen when you add a Cavani or an Ibrahimovic into the mix. Even though they were passed it, they showed us what a high-class CF could achieve.
One of our biggest issues I feel is that we have to work really hard to score goals. We very rarely, if ever, score 'cheap' goals because we don't have the players with the instincts to score them. We don't score many headers, or tap-ins, or deflected goals, or goals from set-pieces.
If we can start to add the sort of 'cheap goal' you get from having a top CF (or two) and we can sort out the GKing position, we could easily end-up 20+ goals better off by addressing two positions.
