Wigan boss Roberto Martinez believes his side face a tougher assignment at Arsenal on Monday night than when they hosted and beat Manchester United.
The Latics caused a significant upset on Wednesday with their 1-0 victory against Barclays Premier League leaders United, who went into the contest off the back of an eight-match top-flight winning streak and had triumphed in all 14 of the previous meetings between the two clubs.
Yet Martinez feels the forthcoming fixture against third-placed Arsenal is a more tricky proposition, and said: "Probably this is an even tougher task. We are going away from home and playing against a side who have been as successful as ever at home."
