It's all nonsense mate. All fluff. Inconsequential. History can just as easily point to portrayals like this:
...and this...
They all fall by the wayside though when the data is added up and the words in the history books written. And it will just state this:
"
Roberto got off to a great first season when records were set for the club in the Premier League, as the Spaniard brought in a more possession based football style. Unfortunately, that standard could not be maintained and performances by and large in the following two seasons in the Premier League were disappointing. Though good runs in cup competitions domestically and in Europe offset that poor league form, Roberto and the club agreed to part company at the end of his third season in the Goodison Park hotseat."
An anodyne and safe assessment avoiding controversy (as they always do) and not without a large chunk of factual content.
In short: there is the history of Everton under Martinez which you and your cohorts would prefer to see written up, then there's the reality based on a mixture of truth and conservative respectability.
