Who in reality uses the 1st team to develop a new team and style, that's what the youth teams are for.I dont think Everton would quickly improve every season until winning the league.
Sometimes you take a step back, build a new young attacking team and take multiple steps forward.
Its a risk to ditch moyes. Its also a risk to keep him and see player development go down the toilet and chances for improvement ignored.
It needs to be done there first so we reap the benefits later.
