I've not given this too much thought because there's a big difference between "offer him another contract" vs. "offer him a contract he'd want to sign". So without knowing the players demands (and other options) it's impossible to say.

However, assuming Moyes plays Alcaraz enough times to trigger his signing.

Who would win:

Everton out of contract XI:

Virginia

Coleman
Young
Keane
[Ok there aren't any other CBs out of contract, so let's say Reece Walsh]

Mangala
Gana

Harrison
Doucoure
Lindstrom

Calvert-Lewin


Everton remaining squad members XI:

Pickford

O'Brien
Tarkowski
Branthwaite
Mykolenko

Garner
Iroegbunam

McNeill
Alcaraz
N'Diaye

Beto

I'd bet on a 0-0 draw.
