Darron Gibson is nearing a return to action after missing the majority of the season through injury.
The midfielder is ahead of his return schedule and is expected to join up with the Everton training sessions in the near future.
Martinez told evertontv: “Darron is working well and is going to join the group very soon. Then it’s about seeing how he can adapt to the demands of working with the group.
“He is out on the grass, though he hasn’t joined in with the group yet. That’s not going to be too far away with how he is recovering. The one-to-one work is showing really well and I don’t think he is going to be too far away from joining in with the group, which is a real success in itself.”
The Blues boss praised the Irishman’s commitment to the cause and means he could still feature in a game this season.
“Remember, when you are out for such a long time you need a bit of a building up period to get your fitness back but all the signs are very positive.
“He is well ahead of schedule and that always pleases me, to see a player get ahead of the timing because it shows all the hard work they put in behind the scenes when nobody is watching.
“The desire of Darron has been sensational in that respect and to have him around the place is a great sign.
“It will be great for him to be involved one way or another before the season ends, even though that would be an incredible and remarkable achievement since looking back on when the injury happened with the national team.”
