David Moyes backed Everton's decision to drop Jack Grealish for Thursday's Carabao Cup win over Newcastle.
Grealish, who is on loan from Manchester City, missed Saturday's defeat at Arsenal due to illness but had started Everton's previous three Premier League matches against Ipswich, Hull City and Chelsea.

Asked about Grealish's absence after Everton's 3-1 win over Newcastle, Moyes said: "It's something I don't really want to speak too much about. It's a club decision, so I support the decision.
"The club are the people you should go to if you're looking for more information."
Everton's press officer moved to bring further questions about Grealish to a close. Asked whether the 31-year-old would be in contention for Monday's Premier League meeting with Newcastle at St James' Park, live on , Moyes said: "I'd never give any team news away."
But Moyes did praise his side's "values" after they weren't phased by Grealish's absence.
"The one thing about Everton and what they've got is they've got really good values behind it," Moyes said.
"All the players stand up to the values, accept the values Everton put out there, what we want from them on the pitch and off the pitch, and from that point of view, the players done a brilliant job tonight."

Everton booked their place in the Carabao Cup quarter-finals with victory at Hill Dickinson Stadium. James Garner, Hayden Hackney and Thierno Barry were all on the scoresheet before Dan Burn's late consolation.
The Toffees will travel to Fleetwood Town in the last eight in December, after the League Two side's win over Arsenal earlier in the week.
Jarrad Branthwaite also remained unavailable for a second successive game as he continues to follow concussion protocols.
