Mirallas missed a crucial spot-kick in the Blues goalless draw with West Brom last week, sparking controversy as he took over from regular and successful penalty taker Leighton Baines, much to the chagrin of his teammates.
The Belgian was then swiftly substituted at half time by Spaniard Martinez, creating a storm around the incident and adding to the pressure currently on the former Wigan manager.
Everton have won just once in the last 13 games, and sit dangerously close to the relegation zone, but Martinez has now said that there was no need for bridge building between Mirallas and the rest of the players.
"The only problem we had was that Kevin missed the penalty. That is the end of the matter internally,” he said.
“Obviously it is something that has been addressed internally and is water under the bridge. Sometimes you feel in a great moment and you want to take a penalty. It is not a negative having players that want to have the responsibility and show they can help the team in specific moments.”
Despite the incident being covered widely and Belgian Mirallas being criticised by fans and pundits alike, Martinez is hoping to have one of his star players fit again for the game against Crystal Palace this weekend.
Mirallas’ substitution against West Brom was said to be because of a hamstring injury, but the manager expects the 27-year-old to be available for Saturday’s game, while James McCarthy could also return.
“We are hoping Kevin is going to be joining the group between today and tomorrow,” he added.
“He is one of the players who has benefited massively from being away and being able to work. He feels a lot stronger and I do feel he has got a great opportunity to be involved in the squad against Crystal Palace.”
