It is overly cautious approach at home that is to blame IMO. We are too slow and ponderous. 2 DMs are just not required against teams that come to park the bus. If we are to persist with 4-3-3, then we must have attacking full backs overlapping at every opportunity, especially with inverted wingers.
At home, I think we are not pressing high enough up the pitch. Against Inter- Milan ( which I consider our best performance under AVB), we started the game quickly, hunted down the ball in packs, never let them dwell on the ball and kept up a fast pass and move tempo. This should be our template for all home games, especially those that park the bus.
Regarding personnel, I would like to see only one DM at home ( either Sandro or Capoue) with two ball players (Eriksen and Holtby). Up front with Soldado should be someone playing close to him (Sig, Lamela or Ade Mk1,) with a winger staying out wide (Townsend, Lennon or Chadli). It is a bit of a wonky, but Rose would/should provide the width down the left.
Start games fast. That is the key. If we score early, the opposition will have to come out. That is the solution IMO.
Oh and DON'T take half the team on meaningless jaunts halfway round the world three days before a PL match.
