The 61-year-old Spaniard has endured his most taxing spell at the helm at Goodison Park in recent weeks as injuries and poor form take hold.
Having made a bright start to the season, the former Liverpool boss has come under scrutiny as results begin to nosedive.
Speaking to BBC Sport, Williams suggested that it was hard to fathom what the Toffees’ modus operandi is.
When I watch the Hammers, I know exactly what they are going to do. They are tough to break down, with some really dangerous players on the counter-attack and they have quality in certain areas. In short, they have a plan. The same goes for every team that is in and around the top of the table, but not Everton. I don’t watch Benitez’s side and think ‘right if the plan comes off, they will win today’ because I am not even sure what that plan is. I also don’t think their squad is good enough, or big enough with as many options as the other teams above them probably do.
This comes just days after former Scotland striker Frank McAvennie claimed it was ‘inevitable’ that the Everton hierarchy would lose patience with Benitez.

Ultimately it’s a results business and of late the proof has been relatively damning.
Benitez was always fighting against the tide on the Blue half of Merseyside and any downturn in form was always likely to bring about questions of this nature.
It would appear that the Spaniard is at least going to get until after the ongoing break to turn things around, both in terms of plan and results.
