I believe the mistakes at the moment are mostly down to the players failings rather than Silva. Of course it is his ultimate responsibility to correct it , but time is required to allow him to repair the problems.
I believe we currently have the worst set of centre backs I have ever seen at the club, although I haven’t seen enough of Mina to be fair.
Ranieri’s success ,whilst impressive ,owed as much to fortune as skill. He essentially inherited a side assembled by a less storied manager primarily to stave off relegation. His appointment gave them the experience needed to take advantage of the failings of the traditional top clubs that season and Spurs lacked experience themselves and bottled it. Respect is due to them though.
It was comparable to the season Moyes guided us,by the skin of our teeth, to 4th.
In both cases the success was flimsy and proved unsustainable. We were bundled out of the Champions League at the first hurdle and finished 11th.
Leicester similarly were unable to repeat their performance and Ranieri was ignominiously dismissed.
For both clubs success proved ephemeral and fleeting and was not evidence of enduring improvement.
It is sustainable and prolonged success I crave for our club, and I am willing to be patient a while longer in the hope we can achieve it.
