Starting at the back. I would never have played Leighton Baines or Phil Jaielka. I would have played Luke Shaw at FB and Smalling at CB.
Then for this England team, I would have played a midfield 3. Henderson and Gerrard worked so well this season because there was a third guy with them. In this WC, they were overrun in the middle easily vs the Italians. And overrun again, although not as bad vs Uruguay. Plus, they really needed a center kid player player who wasn't scared to play a forward pass with some sort of tempo. Everything was so slow.
And up top. I would have played Sterling and Sturridge on both sides of Rooney taking Welbeck off. Both Liverpool players play there for their club, and could have came into the tourney and not really missed a beat. Rooney is at his best centrally, which makes him playing out left and Sterling centrally vs Italy mind baffling.
