Rather than looking at it as 2 wins in 16 (which itself is a terrible statistic and is relegation form) it should also be coupled with the fact that we have such a terrible loss record despite being I think it was the 4th highest scoring team in the league.
Our defence is one of the worst in the division and we have becoming terrifyingly vulnerable to late goals since March last season with no end to that trend in sight.
You could argue that RM has access to one of the youngest attacking squads in the division and only a few sides have signed more players than us once you compare to when we first hired him. The damning statistic here is how few of those players are still in his first team plans, how many he has had very public fallings out with and how many were just frozen out and forced to be sent on loan.
This to me screams of a manager who cannot organise a defence, is poor at game management, poor at man management and sadly is over fixated on possession as a statistic than on doing something with that possession - I don't know how to find it as a stat but I think we must be one of the lowest sides in the division for shots per minute in possession.
