Roberto Martinez will not waste any energy on wondering if he has a future at Wigan despite his side's 6-0 thrashing at the hands of Chelsea.[LNB] The Latics suffered the heaviest home defeat in their history in being thumped by a Chelsea side who have started the defence of their Premier League title with successive 6-0 victories.[LNB]In their last five league games overall they have scored 29 goals, which also includes an 8-0 romp over Wigan at Stamford Bridge on the final day of last season.[LNB]After last Saturday's humiliating 4-0 home loss to Blackpool, these are dark days for Martinez, and it is now a question of how much patience owner Dave Whelan has in the Spaniard.[LNB]"The chairman is a passionate man, he loves football and he wants the best for Wigan Athletic," said Martinez.[LNB]"He knows the situation we're in, and he couldn't be any more supportive."[LNB]Asked specifically if he feared for his job, Martinez added: "I can't waste any energy or time worrying about that.[LNB]"I need to worry about how to get the team to perform for 90 minutes because it's a young side that is capable of the best, and we have to build on that, and that is my focus and concentration.[LNB]"I've huge belief in this group of players. I know we're going to get the results from the potential we showed in the first half.[LNB]"We're working towards the aim of staying in the Premier League and that's the focus."[LNB]Wigan's first-half performance was in stark contrast to the display against Blackpool as there was energy, enthusiasm and endeavour.[LNB]But they still went into the break a goal down courtesy of a tap in from Florent Malouda after Chris Kirkland had superbly saved a Frank Lampard effort.[LNB]After the break, two quick goals from Nicolas Anelka sealed a win that was underlined in the final 11 minutes with a brace from Salomon Kalou and one for Yossi Benayoun.[LNB]"I'm feeling low for the players because they didn't deserve that," said Martinez.[LNB]"Today was a big day for us because we needed a response after what happened on Saturday, and we had that in the first half.[LNB]"I was as proud as I can be of the efforts of the players and the way we played.[LNB]"But in the second half we need to learn not to be that naive and when the third goal went in, in a way we accepted the game was finished.[LNB]"The result was very hurtful, and we have to stop allowing them to happen.[LNB]"We have to build on the first half because when you are better than Chelsea in every single department, it shows you the quality and potential of the squad."[LNB]After opening the season with their thrashing of West Brom, and on the back of this rout, there is currently no stopping Chelsea.[LNB]"We have started well this season, scoring a lot of goals, playing good football," said Chelsea boss Carlo Ancelotti.[LNB]"But the first half was tough. Wigan played good football, put pressure on us, and we were not able to play our football as there was no space.[LNB]"But we defended well, didn't give them opportunities and we waited to score, which is important because in football you have to defend and attack.[LNB]"It's impossible to have total control of the game with possession, sometimes you have to defend, and in the first half we defended very well.[LNB]"Maybe they spent a lot of energy in the first half because in the second it was easier for us as we had more opportunities to score."[LNB]Explaining why he feels teams fold against his side, Ancelotti added: "We have a lot of skills.[LNB]"Our best quality is we are able to counter attack fantastically well, strike fast and with ability.[LNB]"When we have space it is difficult for the opponent to control us.[LNB]"But it is impossible to think we have to score six goals in a game all the time because this is not real football, this is PlayStation football."
