Martinez seeks more 'big four' success

Roberto Martinez believes his side have broken down a mental barrier with their recent performances at Liverpool and Chelsea.

The Latics head to Arsenal on Monday looking to follow up their stunning midweek win over Manchester United with an equally unlikely triumph. At the start of March, few would have given Wigan any hope of Barclays Premier League survival. However, since then they have beaten United, won at Anfield and were only denied a positive result at Chelsea due to a series of dubious decisions, including bad offside calls for both Blues goals. For a side who had not been able to beat one the old 'big four' for so long, it marks a substantial change in fortune. And Martinez wants to build on that at the Emirates Stadium. "We are capable of getting results against anyone," he said. "We proved that against Manchester United but also against Chelsea and Liverpool. Those games allowed us to break a mental barrier that we had in the past. "We went to Anfield and won, and in my eyes we beat Chelsea, even if we didn't win the game. When we are at our best, and we have to be perfect, we are a competitive side no matter who the opposition is."
