The problem these new managers face, those who have won nothing of significant ie Sherwood and Rodgers, is they need to provide evidence that they are tactical geniuses.
With Sherwood he tries to embody the straight talking of past managers, the Cloughs, Shankleys of the world. WHICH is well and good but when you lack the funk in your trunk you look a bit silly.
Rodgers is the same, he claims to be a tactical genius, his players are outstanding when playing in HIS system under his amazing tactics.
If he had won something his claims would not be so hollow.
It us a case of the emperors new clothes for the both of them.
Don't question Sherwood or BR or you will discover the foundation is built on quicksand.
