However, the Spaniard has moved quickly to bring several members of his trusted staff from Wigan over to Finch Farm, with their arrivals confirmed on Thursday evening.
Graeme Jones a former Wigan striker (among a number of lower division sides) who replaces Steve Round as the club's assistant manager.
Jones played alongside Martinez at the Latics and were re-united when the Spaniard was appointed Swansea manager in 2007.
Inaki Bergara also formed part of Martinez's coaching set-up at the Liberty Stadium, following him to Wigan and now to Everton, where he replaces Chris Woods.
His playing career took in spells at Athletic Bilbao, Alaves, Murcia, Real Sociedad and Logrones before a brief spell coaching at Athletic Bilbao, prior to his move to Wales.
Kevin Reeves has joined the club as new chief scout. The 55-year-old saw his playing career cut short due to injury at the age of 26 but picked up coaching experience at Burnley, Birmingham, Wrexham and Swansea - where he worked with Martinez.
Richard Evans meanwhile joins as head of player performance, which covers both physiotherapy and sports science - i.e. keeping the players as fit and prepared as possible. He also first worked with Martinez at the Liberty Stadium.
With the backroom team now in place, hopefully focus can now be switched towards getting the players ready for the new season and, of course, bolstering the existing side with new faces.
