The Latics are currently embroiled in a tense relegation battle and the Spaniard is refusing to consider his players' long-term futures until the season is finished
Martinez's side are currently three points adrift of Aston Villa in the relegation zone but despite having the likes of Maynor Figueroa, Franco di Santo and Antolin Alcaraz out of contract this summer, the Spaniard has revealed he will be putting talks over a new contract to one side for the time being.

"Everything is surrounding the final five games in the league and making sure we achieve our aim.
"The club is the priority. At the end of the season we will look into every individual because there are four or five who need to be given some consideration about the next step in their careers.
"At the moment, we are at a stage in the season where everything gets frozen because the only thing that matters is the football club."
Wigan have been rocked by the loss of Alcaraz for three weeks, which would mean his return would be in the FA Cup final against Manchester City, but Martinez believes the likelihood of the Paraguayan appearing is doubtful.
"As it stands it would be difficult to tell," he added.
"We are talking about three weeks since it happened. It will be touch and go. It depends how quickly he can recover."Alcaraz will definitely miss out on Saturday's clash with Tottenham, with skipper Gary Caldwell expected to step in at the heart of defence.
The Scot was dropped after being run ragged in Liverpool's thumping 4-0 win at the DW Stadium but was restored to the starting lineup for last weekend's defeat to West Ham.
And ahead of what will surely be another stern test for the centre-back, Martinez praised Caldwell's presence at the club.
"Gary, playing or not playing, is vital to this football club," he continued. "He is the club captain and his influence to the players is very important.
"He is fresh and ready to step in and help the team."
