More focus on the offensive side of the game often leasd to more goals conceded as well.
I think it's not that easy to deliver more goals without letting more in.
Usually I'd say you're absolutely right but I think we're OK here. Our problem isn't necessarily creating chances, because we've had plenty of those - balls hitting the woodwork, missed penalties, Kuyt heading wide from 6 yards out, Carroll blocking goal-bound shots, super-keeper displays from Jon Ruddy - it's mostly just finishing them. Even Suarez, as incredible as he is, does not seem to have the predatory instinct that made Fowler and Owen so good in their day (and going back further, Rush, etc.). Of course, you could argue that players like that only come along once every 10 years or so, but I think that even a decent striker that has a bit of a cutting-edge would do us a world of good. We don't need a systemic change in our build-up and attacking play, we just need to be more clinical. And I'm more than sure that our defense can cope with whatever is thrown at them at the moment, they have been outstanding.
