The Blues boss says his summer signing is fit enough to start against Chelsea next time out.
He is currently on duty with Argentina as they take on Bolivia and Mexico, but is far from lacking fitness, with River Plate’s season already underway, and Martinez says he is ready to slot into the Blues side when they take on Chelsea after the international break.
“I feel that after the break he will be ready to join the group,” he told evertonfc.com.
“Clearly, he is going to need a little bit of an adaptation period because the British game is very, very different - especially for a player that is in the last line. But, in terms of being available, I expect him to be fully fit and ready for the Chelsea game.”
Should Everton switch to five at the back?
With the £9.5m move having been a big one for the Blues, it would be a surprise to see Mori spending his time on the bench.
Perhaps then, Martinez is planning on a change of system for his side, potentially looking at playing with a back five, allowing his full-backs, namely Seamus Coleman and Leighton Baines, to be more attacking outlets.
It would be a move that would make sense, as not only would it allow those two full-backs to have more influence going forward, where they are arguably strongest, it would also solve his issue of the missing number ten.
The Spaniard was keen to add a playmaker this summer but failed to do so, and while Ross Barkley has impressed so far, moving him into a more central midfield role is unlikely to do too much damage to his development.
Given it was a formation he adopted at Wigan Athletic as well, it makes it all the more plausible. However, he is unlikely to change from his favoured 4-2-3-1 formation at present, although the option is certainly there should he decide a change is necessary.
