Wigan boss Roberto Martinez is relieved that midfielder James McArthur is back to full fitness now.
"James has been through a very demanding start to the season, because after an hour or so on the pitch his back begins to stiffen up and against Chelsea and Stoke he tired towards the end of the game when the tempo was high," he explained.
"But he has such a strong mentality which allows him to be available and I think the two-week period we've had has helped him with his full recovery.
"Fortunately we have a large squad and the games we play in every competition are so important in building that understanding the players have of the roles required when they take to the pitch.
"All the players have that understanding now and can bring something different to the set-up as well which is a real strength we have."
