With Delph out, we have no midfielders prepared to carry the ball forward ..... they all pass sideways or back and that means 50 passes to cross the half way line, it means next to no service to the forwards and it means no goals will be scored.
How obvious does it need to be to Lambert that somebody has to be a risktaker and the only lad I have seen this season - aside from Delph - who is prepared to take risks is Grealish and he don't make the bench !
Without the forward momentum from the midfield, the forwards are too easy to pick up and mark tight. When we run from midfield, we challenge the opposition backs and that creates space for the forwards ..... basic U12s coaching FGS !!!
