Perrenial survivors Wigan are scrapping for their lives again and slipped back into the bottom three after successive defeats against City and West Ham.
However, the FA Cup finalists showed typical fighting spirit with a run of one loss in five before those setbacks.
We came from 1-0 down to beat City 3-1 in a memorable victory at the Lane on Sunday and Lewis insists we have to take that mentality to the DW Stadium.
“It’s a tough place to go, they are fighting for every point, every point is vital, but that’s the case for us as well,” said the midfielder who made such an impact off the bench against City.
“I saw the match where Wigan beat Everton 3-0 (in the FA Cup) and we’re all aware of what they are capable of.
“We have to go into the game with the same mentality as the game against City and try to put them under pressure, play our game, try to get early goals and get the job done.”
Victory would move us into third place in the table with Arsenal (home against United) and Chelsea (home against Swansea) in action on Sunday.
