Unsurprisingly, they look jaded and legless. Having been really lucky with injuries for the previous 2 seasons, they've now had a bad run of injuries to key players. The squad is not deep enough to maintain the standard of their best 11 and some players are now being overplayed when they should be being rested.
Most of their their creativity/assists used to come from their full backs but defensive insecurity means that they can't bomb on as before - they have no creativity in midfield, hence no goals.
I expect they will come again once injuries heal and players get a decent rest.
