There was an article before the world cup where Southgate was asked "what happens if the back three system isn't working! Will you change it to a back four?" His reply was along the lines of the back three is the answer to all the problems and we make it works no matter what
With regards to England not having a talented squad, then surely we should play a system that gets the best from the players we do have, rather than shoehorning them into an unfamiliar one where our better players are weakened
Walker is one of the world's best right backs and played at centre half
Sterling is far more dynamic and a real threat when coming in from wide positions yet was played in a David Silva position
England should have set up like a downmarket City
Starting with a back four with Delph at left back who moves into midfield to create the extra man when we are in posession
Henderson the screen
Rashford and Sterling wide
Kane up front

Frighten the opposition with electric pace out wide and control the midfield
