Roberto unconcerned by Wigan plight

The Latics host Liverpool on Monday night having failed to win in their last seven league games, a sequence that has left them in 16th place, just a point above the relegation zone. However, they are also only two points away from 13th spot and, as remains the case throughout the division, there is still everything to play for. The visit of Liverpool is one of five games Wigan have coming up against teams in the current top six, but they also face five of the bottom eight in their remaining 11 fixtures and Martinez is confident his side can change the complexion of their season if they pick up a positive result over the next few weeks. Asked if he was starting to worry about the team's league position, Martinez said: "No, because it is always about ourselves. It's going to be a really tight finish. You are looking at probably one of the most exciting Premier League campaigns ever. "Three teams are trying to win the title, then you have four teams going for fourth spot and eight teams trying to avoid relegation. "It is about reaching certain standards, being consistent with them and not allowing your football to be affected by your position in the table. "But I feel that the group we have now is as strong as it has been all season, we have come a long, long way and probably now we are one result away from really finishing the season strong. "We are in the middle of a period where a couple of big decisions went against us and we couldn't really react to that. "But it is the time to focus on ourselves and make sure that we affect the games so we get those decisions going our way." Martinez feels luck has been against his side in recent weeks, with Jermain Defoe's opener allowed to stand in the 3-0 defeat to Tottenham despite the England striker appearing to be offside, and no action being taken by referee Anthony Taylor last weekend when Liam Ridgewell clattered into James McCarthy during the 1-0 loss at Birmingham. McCarthy suffered an ankle injury from the challenge, in which referee's assistant Trevor Massey had to be carried off after being struck in the face by the tip of the corner flag. Taylor chose not to show Ridgewell a card for the tackle and the Football Association this week dismissed reports that retrospective action would be taken against the player. Martinez maintains Ridgewell should have been sent off, but McCarthy escaped without any lasting damage and with the match now over, the Latics boss feels it would be of no use to his team's fight for survival if the defender was hit with a suspension. "What you need is the punishment for the action to be handed out in the game," Martinez said. "At that moment, we were well on top and it would have been a big, big decision in the game that would have helped us get the rewards we deserved. "It would have been ridiculous to look back at it now and punish the team by taking out one of their best players for a game against another team who could be fighting for the same aim that we are. "That would make Birmingham weaker for a game against a team who might be one of our rivals, and the whole thing would make no sense to me at all. "If officials don't see something during a game, that should be it. There should be no action afterwards." Meanwhile, Martinez confirmed former Portsmouth defender Dusko Tosic would not be joining the club. Tosic, who is a free agent after a short stint with Pompey, was linked with a move to the DW Stadium but according to Martinez, the Serbia international has decided to play elsewhere. "He is someone we knew was available but we are not going to do anything with that situation," said Martinez. "I think he has a few options and the player has made his mind up."
