Peterborough manager Darren Ferguson believes his side have "a great chance'' of dumping Premier League West Brom out of the FA Cup in Tuesday's third-round replay.
Tony Mowbray's side will arrive at London Road on the back of a dire run of away form which has seen them fail to win since September.
Albion did knock Ferguson's men out of both the FA Cup and Carling Cup at London Road last season en route to the semi-final, but the Posh boss believes that an upset could be on the cards.
He said: "We know we will have to play at a similar standard to what we did at the Hawthorns, because West Brom are a very good side.
"It isn't a case of missing out in the first game. We still feel we have a great chance of progressing if we play to our potential.''
Striker Craig Mackail-Smith's late goal earned Posh a 1-1 draw at the Hawthorns in the first tie 10 days ago - but Ferguson has seen two subsequent league fixtures postponed because of the freezing weather.
The extra rest has allowed defender Tom Williams to regain full fitness after a knee problem, but Ferguson admits he would rather have played straight after their excellent performance.
He said: "All of the lads are really looking forward to the game and have been champing at the bit really, because we have been without a game for the last week or so.
"When you play so well, like we did at the Hawthorns, you really want to play straightaway. But we are ready and raring to go.''
Peterborough have already sold more than 5,000 tickets for the match.
Ferguson will be without on-loan midfielder Andrew Crofts, who is cup-tied after playing in an earlier round for parent club Gillingham.
Defender Chris Westwood has joined Cheltenham on a month's loan, while Liam Hatch has returned to Coca-Cola League Two Darlington on loan until the end of the season since Ferguson's side last played.
Fellow striker Scott Rendell is back in contention, after his similar move to Cambridge fell through, and Ferguson's only long-term absentees are Jamie Day (back) and Shane Blackett (shoulder).
