Before any individuals are assessed, here's a look at the likely pattern to proceedings and the subsequent clash of styles.
West Brom will begin the game entrenched in their own half, hoping to make things as difficult as possible for the hosts. After gaining possession, they will look to counter-attack at pace and be clinical on the break.
Space will be targeted behind Leighton Baines and Seamus Coleman, and the likes of James Morrison and Graham Dorrans will look to isolate defenders and breeze past them one-on-one. If that setting remains, Everton will find it hard to break down the visitors, who would have a strong chance of at least claiming a point.
The hosts on the other hand will look to dominate possession and play in West Brom's half. However, to counter their opponent's potentially negative outset, Everton will need to play deeper and entice the Baggies out from the back, otherwise it will be extremely hard to create chances.
If they can lure them forward, Martinez's side will look for a combination of crafty movement, sharp touches and incisive passing to play through the opposition. As with West Brom, attacking at pace following a turnover will be crucial to the Toffees.
Ignoring set-piece goals, or obtaining a lead via a stroke of good fortune, whichever side is forced out of their initial strategy will struggle.
