I guess I started to really get excited thinking about this and did what any self-respectable fan would do...
Drew up a new formation.
If we're all healthy*, it would leave us with 4 CBs with real quality (Caulker, Dawson, Vertonghen, Kaboom) 3 of which can pass it about and make runs into the opposing half (Dawson's just not this type). And going with what we have now** it looks like an extremely solid option both defensively and in attack.
you could change out Walker with Lennon if you wanted, but it looks near impenetrable defensively, and adding a clinical finisher at striker i'd say its a good option to look into.
Should challenge for a lot more corners as well. Caulker, Kaboom, Vertonghen, Sandro, Bale all can head the ball well.
opinions??
*big if...
**i know i know, we might not have Defoe, Ade, Modric or Bale.
