Martinez comes with a glowing reputation enhanced by Wigan’s FA Cup triumph last season.
“All I want to do is try to be humble enough and hard-working enough to take to that magnificent job into the next level,” Martinez, 39, said.
“(There is) huge pressure but I’m extremely proud of that pressure, what David Moyes has done at Everton in the last 11 years is set real standards… and given an incredible platform for the next man to continue.”
