Pokhara: Despite interest from Aston Villa, Roberto Martinez has decided to stay at Wigan Athletic. Martinez spoke with Villa chairman Randy Lerner after the American made it clear that the Spaniard is free to fill the position left by Gerard Houllier if he wants to. Wigan chairman Dave Whelan was happy to grant Martinez permission to speak to the midlanders although he was confident that he would hold on to the 37-year-old.
