A lot of Everton fans must be a little frustrated at banging the same drum over the system that their side are using.
Five-at-the-back is not an inherently defensive system and a lot of clubs across Europe manage to use it to great and exciting effect with the players they have at their disposal. You can't really dispute that.
However, the Blues have never really been one of them. Granted, playing in a similar formation to this did a job at the back end of last season to keep them in the division, but fans now are desperate to see that evolve into something else.
