Roberto Martinez's arrival at Everton has brought a significant change of style on the pitch.
He's altered an often reactive team under David Moyes and introduced progressive methods, with an emphasis on possession and control.
While such drastic changes have occurred in approach, there haven't been as many changes in personnel, as yet.
Everton's current back five were all mainstays under Moyes, while Kevin Mirallas, Steven Pienaar and Leon Osman remain in midfield.
Martinez has only overseen one transfer window and has been wise not to introduce too many new faces too soon; however, over time, he will look to forge a team in his own image, and a few more of Moyes' regulars will be cast aside.
Here's a look at the Toffees' most vulnerable starters, who may struggle to stay in Martinez's long-term plans.
