I'm with Davek here. I'm pleased with most of our game atm. We are sound enough at the back with brilliant attacking full-backs and we have a superb midfield that can go toe to toe with anyone and out-pass/out-battle them.
The last element we need and are missing atm is that link between our creative players and the striker. We were missing it before Lukaku got injured and have missed it with other players who have replaced him recently. We've often got by on spectacular goals from midfielders or the full-backs this year (Swansea, Norwich and Villa spring to mind).
I'm not sure, personally, what needs doing, whether it's a change in personnel up top or just perseverance with the current system to make things click, or players (e.g. Mirallas/Barkley) to return to form.
It'll be hard to sort this out if RM thinks we need new players, as top attackers don't come cheap. Fortunately for teams like the RS and Brendan Rodgers, they were already blessed with a world class player like Suarez when BR took over and on top of that, were able to spend £12m on a striker last January to complete their strike force. Having £12m before player sales and spending £22m on a single player are the kind of things we can only dream of, so unfortunately for RM, he's got a bit of a task on his hands.
However, if he was to get a top class attack on the same wavelength as the rest of our team, I've no doubt we would be a top 4 side. Looking at our performances away at the top 4 this year (bar the anomaly at Anfield) we've been more than a match for all of them.
