"The result was the main thing. I don't think we played well at all, we were very scrappy which is unlike us - but it's another three points and we'll take it," McArthur is quoted as saying by Football365.com.
"We're better than we showed today but we had to display a lot of resilience to win the game. We've got another game before the FA Cup semi-final, but when it comes around, we will give it out best shot."
Wigan are back in action on Tuesday night when they face Millwall.
