Roberto Martinez says Wigan's FA Cup third round win shows strength in depth

Roberto Martinez believes Wigan's success in their FA Cup third round replay at Bournemouth shows his side's strength in depth.

Wigan will make the short trip to Macclesfield in the fourth round after the Blue Square Premier side shocked Championship leaders Cardiff City. "It's going to be a difficult tie," Martinez said "They deserve all the media attention they get. To beat the Championship leaders is not an easy task."
