Speaking about the game, Adkins said: "The Premier League is a relentless division. We had opportunities and didn't take them. You have to be ruthless, the harsh reality is you will be punished if you are not.
"Wigan scored their two goals with good finishes and our goalkeeper Kelvin Davies had nothing else to do but pick the ball out of his net.
"Goals change games, and 1-0 down with 20 minutes to go, you change your formation to get back into it; that is my responsibility.
br>'But the 4-4-2 saw them have far too much of the ball."
