Speaking last week, Moyes said of Mykolenko: “He’s [Mykolenko] got a chance for Sunday, the extra day might help, we’ll see.”

That suggested that Mykolenko wasn’t going to be out for a long period of time, and that if he didn’t make it against Hull, then he would probably be back for the Chelsea game.

Everton have now dropped some training footage ahead of that game, and it potentially offers a clue about the full-back.

Given that update by Moyes ahead of Hull, Evertonians expected to see Mykolenko back with the group ahead of this weekend’s game with Chelsea.

But ominously, he does not appear in the footage Everton have released today on social media. It’s unclear what day exactly the footage was taken. But Mykolenko not appearing is slightly concerning.

So far this season, he has been one of Everton’s most consistent performers. And against Hull his absence arguably had a detrimental effect on the backline. It meant Jarrad Branthwaite moved over to that position, and he didn’t look comfortable throughout.

Branthwaite moving over also saw Michael Keane partner James Tarkowski in the middle. The Tarkowski-Branthwaite partnership has been one of the highlights of the season so far, so that was disrupted.

Moyes will speak to reporters at his press conference tomorrow and be able to provide an update on his condition. Hopefully, he will have shaken off the problem in time for Saturday’s game at Hill Dickinson.

Garner or Maitland-Niles must replace Mykolenko if he can’t play

If Mykolenko cannot play on Saturday, then Moyes should avoid putting Branthwaite at left-back again and instead plump for either James Garner or Ainsley Maitland-Niles.

There are simply too many drawbacks to putting Branthwaite out wide, including the fact that it is a far more physically demanding position for a player who has been quite fragile since being at the club.

Chelsea are very dangerous in the final third and Joao Pedro is having a particularly good start to the new season.

It would make far more sense to have Branthwaite back alongside Tarkowski where he has been shining.
