Surely the frailty we have at the back this year as compared to last, is that last year we were playing with two holding midfielders-Walton and Wotton-who were protecting Maxi and Purse. We were also playing then to hold on to the point we had at the start of the game, and were keeping a fairly settled formation. This year the formation, and players ,have changed regularly, and it seems inevitable when this happens that the understanding and shape suffers.
