England need to win to finish top of the group and reach Brazil 2014 automatically, given second-placed Ukraine take on pushovers San Marino, and Poland have nothing but pride to play for.
"We go to England now," said Lewandowski, Borussia Dortmund's Bayern Munich-bound striker.
"We know we have a lot of fans out there who will come to the game. We don't stand a chance of going through, but we want to go to Wembley and at least allow our supporters a little fun. For sure we won't be favourites."
Poland captain Jakub Blaszczykowski added: "It doesn't matter that we only have honour to play for. Matches at Wembley are always very important to us.
"There are sure to be many Polish fans there, and we want to thank them with a good game and the right result."
