Uwe Rosler's Latics have already beaten top-flight opposition in Crystal Palace and travel to Wales with an unlikely defence of their FA Cup crown still possibleWigan's defence of their FA Cup crown continues with a tricky fifth-round trip to Premier League outfit Cardiff City on Saturday.
The Latics are on a 10-match unbeaten run in the world's oldest football competition, including a famous 1-0 triumph over Manchester City in last season's final when Roberto Martinez was at the helm.
Wigan have since dropped out of the Premier League, meaning that Uwe Rosler's men would be the first team in 34 years to win the competition from outside the top flight if they can repeat their success, with West Ham the last team to achieve the feat in 1980.
Cardiff have failed to register a victory over the Lancashire side since a 1-0 win March 1997, a run that stretches back for 10 matches, though Saturday's encounter will mark the first meeting between the two teams since April 2005.

Both Rosler and Cardiff boss Ole Gunnar Solskjaer joined their respective clubs this season. The former has fared slightly better in his new role, with eight wins from 15 matches, while the latter has emerged victorious from three of eight.
The pair have history as cross-town rivals for two years from their playing days at Manchester rivals United and City and their pasts are further intertwined, with the Norwegian having replaced Rosler as Molde boss in November 2010, despite the German staving off the threat of relegation that season by going unbeaten in the last eight games.
Solskjaer will be wary of a potential banana-skin, with his side having recorded just two wins from their last seven matches in all competitions, while have the last two fixtures have seen them fail to score.
The Bluebirds manager - a two-time winner of the competition as a player in 1999 and 2004 - will hope that striker Fraizer Campbell can continue his form in the cup, with the one-time England international netting in the wins over Newcastle and Bolton in previous rounds.
Juan Cala could make his Cardiff debut at centre-back after signing on a free from Sevilla but club captain Mark Hudson remains a doubt with a hamstring injury.
