Saturday's result against Rovers ended Wigan's eight-match losing streak in the Premier League, but they were aggrieved not to have come away from the DW Stadium with a victory. Rovers' second goal came when Morten Gamst Pedersen dribbled the ball straight from a corner before crossing for Junior Hoilett to score. The incident left Martinez - whose side are bottom of the table - fuming, and the Spaniard believes the sense of injustice within the Wigan camp will carry into the contest at the Stadium of Light this weekend. "Sunderland are playing at home and they will feel, with the money they have spent, that they should be beating a team like ours," Martinez said. "That is a level of expectation that you can understand, but we are hurt from the weekend and we feel we are owed points. We need to go out there and make sure we can get that." Martinez was encouraged by the way his side played against Blackburn - it was the first time they had scored three goals in a match this season - and is confident they can finally register their first win since August on Saturday. "The team is playing at a good level, but we need to create that momentum, belief and confidence that comes with positive results," he said. "I just saw a turning point on Saturday and I feel we are capable of going anywhere and performing in a manner good enough to get three points." Referee Andre Marriner, who allowed Hoilett's effort to stand, is not taking charge of a match this weekend and Martinez revealed he had discussed the incident with Mike Riley, manager of the Professional Game Match Officials Board. "I spoke with Mike Riley and he faced the situation," Martinez said. "I think he was a real credit to the association and to the referees in general. "Obviously, it is a very difficult action to explain, but I just want to move on. It is not something that you are going to see on a football pitch too often and I saw it as very careless at that moment. "It is something you need to get right. It is not down to judgement, it is probably one of the few aspects where refereeing in a game is black and white, with no grey areas. "You have to deal with it with a little bit more care." At the time Martinez claimed that Wigan's "small voice" was counting against them, and today reiterated the suggestion that smaller clubs were not getting the rub of the green with regard to refereeing decisions. He added: "You just feel that sometimes, as a club like ours, you get too many sloppy errors that you wouldn't get at other venues in the competition. "That frustrates you. We all accept that there are errors due to human judgement, but it is all too often that it happens against us." Despite those sentiments, Martinez does have sympathy with officials when it comes to determining whether or not a ball has crossed the line. Football Association general secretary Alex Horne has indicated that goal-line technology could be used in the Premier League as early as next season and, asked if it was something he would welcome, Martinez said: "Absolutely. "It is very unfair for referees to have to make calls where they can't really tell - it is impossible to tell. "Goal-line technology is a must if we want to be as good as we can be. It would help the referees and we need to give them as much help as we can. "I would think goal-line technology would take our competition to a new level."
