The Latics have reached the semi-finals of the FA Cup for the first time in their history but Martinez has left no-one in any doubt of the club's priority - survival.
"The moment you, as a player, lose your focus you lose any involvement in the cup so it is a very straightforward situation," said the Spaniard.
"What is important is now everyone has a unique opportunity, a great prize, to play at Wembley which is a great reward for any player in their career.
"Clearly every place is up in the air and the next three games in the league is going to be where the positions for Wembley are going to be decided.
"The best way to prepare for Wembley is with your level in the league and I don't see it as a distraction at all. I see it as an opportunity for players to be rewarded with their good form in the league.
"Believe me, no-one will lose their focus here of what is the priority and that is the league."
Martinez believes the Latics are embroiled in the toughest relegation battle of his four-year reign at the DW Stadium, with just 10 points separating 10th-placed Fulham and bottom side QPR.
"The teams in the bottom three I don't think are going to stay there, there will be other teams involved and it will go down to the final day once more," he said.
