It is frustrating. Even more so cos I'm unsure that the answer is simply giving Suarez more support.
It goes deeper than that.There's a gulf at times between the defence & the midfield, or between the midfield & front three.
It's true that the answer isn't confined to supporting Luis Suarez better, but getting that one thing right would be key to resolving so much else. As well as giving us more of a cutting edge, the lack of which has cost us half a dozen or so points this season, it would improve the balance of the whole side. Ditto its morale, I suspect, as we see more goals going in and more points on the board.
