The Spaniard has discovered a successful formula in the last month and ever since their quarter-final victory at Everton he has kept faith in the same players.
In the last five matches he has made just one change - replacing goalkeeper Joel Robles for previous first-choice Ali Al Habsi for last weekend's Wembley win over Milwall.
He has been rewarded with four wins - two in the cup - and a draw, which has crucially contributed seven points to their relegation battle.
And while it has meant the likes of club captain Gary Caldwell and Al Habsi have been sidelined, Martinez insists the players understand it is for the greater good.
"Competition for places has stepped up a percentage, the level of training has increased and we have been unbeaten in the league since then," said the Spaniard.
"Players are desperate to help the team. There are no individual cases, from now until the end of the season it is about what we can do as a football club.
"There is a bigger role than playing or not playing. Everyone is aware the achievement as a team is more important than individuals.
"We have players who are fully aware of what they need to bring to the team and everyone is expecting to be used from now until the end of the season."
