Sam Allardyce is confident West Ham's win at QPR will provide the side with the confidence needed ahead of their clash with Wigan.
The trip to Loftus Road on October 1 was the side's first away win of the season and the Hammers go into Saturday's game at the DW Stadium sitting seventh in the table.
And following his side's 4-1 thrashing of Southampton last weekend, Allardyce is challenging his players to replicate that performance on their travels.
"We have got a chance to try and go back-to-back," said Allardyce.
"We had a very, very good performance and a very good victory at QPR last time out away from home so that should give us a lot of confidence going to Wigan."
Wigan boss Roberto Martinez has regularly been using a 3-4-3 formation this season and Allardyce knows his players must adapt their approach accordingly.
Allardyce added: "I just think we have got to be tactically right on Saturday because of the system they play, we come across that system hardly ever.
"So we have got to make sure we can combat that system tactically and make sure we nullify its strengths and try and expose its weaknesses, if we do that we will give ourselves a great chance of getting a result."
West Ham have recorded four wins in their opening eight league games on their return to the top flight.
