West Ham manager Avram Grant insisted his side can climb to mid-table safety after their 3-1 home win against Wigan.They remain bottom of the Premier League, but only a goal difference from Wolves and two points behind Wigan. [LNB]Grant said: "We are only nine points from the middle. That's (a gap) you can close with more than 20 games to go. [LNB]"We have played only 15 games, so at the moment it does not really matter if Wolves win or the others do - we need to do our job." [LNB]The Hammers had set up the game against fellow strugglers Wigan as the "Save Our Season" game and Valon Behrami, Victor Obinna and Scott Parker put them 3-0 up at Upton Park.[LNB] I could get used to this winning feeling again IronSpeakEasy Wigan substitute Mauro Boselli failed to convert a penalty for his side when they were 2-0 down before Tom Cleverley scored a late consolation goal for the third-from-bottom visitors, who are just two points ahead of West Ham. [LNB]"It was a good win and a convincing victory, I am happy for us and hope it is only the beginning," said Grant. [LNB]"We played like we have all of the other games, but were more efficient [against Wigan]. [LNB]"We won, this is the difference and this is the name of the game. [LNB]"We started a bit nervous, which you can understand from our position in the league and the last game [when we lost] at Liverpool. [LNB]"But the players always tried to do the right thing, were fighting and they have responded. [LNB]"We are trying to build a good mentality, which is important." [LNB]Grant also dismissed speculation concerning his own future at the club following the poor start to the current campaign.[LNB] We just weren't ourselves, and that is where the work is going to be Wigan boss Roberto Martinez "I never think about myself, I am in a job where there are always rumours," said the former Chelsea and Portsmouth boss. [LNB]"I just need to concentrate on my job, that is what I have done all my life and will do in the future." [LNB]The Israeli brought in Wally Downes as his defensive coach this week and, although there are rumours former Hammers favourite Paolo Di Canio could come in as a coach to the strikers, Grant said no approach had been made to the Italian. [LNB]He added: "There have been a few names, but I did not speak with him. [LNB]"We want to build West Ham step by step and are looking for more specific coaches which will do specific jobs. [LNB]"For me, Di Canio is always welcome at this club. He is very respected and I had the honour to see him playing a few times, he was a great player. [LNB]"If he can teach our players how to play like him, I will take him!" [LNB]Wigan boss Roberto Martinez was left to rue the manner of the goals his side conceded as he believes his players failed to do themselves justice. [LNB]"We conceded three very cheap goals for our standards, and that is something we will work on," said Martinez. [LNB]"We had a few players missing, but that is not an excuse. You got the feeling nothing was going our way. [LNB]"There was a good opportunity to get back into the game with the penalty, and then even at the end we got a good goal ruled out. [LNB]"It is quite clear to me the things we need to work on, but I was pleased with the reaction towards the end. [LNB]"It was a day of a real test of character, and that was there, but in football you cannot concede cheap goals, otherwise you are making things very difficult. [LNB]"We just weren't ourselves, and that is where the work is going to be."
