Peterborough v Ipswich: Victory at Peterborough United tomorrow will be sweet revenge for the scarred Blues stars hit for seven at London Road last season.

But on-loan Town striker Daryl Murphy insists survivors of the Posh capitulation, such as Tommy Smith, Michael Chopra and Aaron Cresswell, must keep their emotions in check.

Ipswich are four points clear of the Championship drop-zone ahead of the crunch clash with second-bottom United, who hammered Town 7-1 in a televised clash in August 2011.

Murphy, who joined the Blues in the week following that heavy defeat, said: “We don’t owe them one but the stakes are so high, we need to go and win.

“After losing so heavily, the dressing room atmosphere was not great when I arrived and it did not help the players’ confidence, but it is not about going to Peterborough and getting revenge.”

The defeat at Peterborough came after a 5-2 home reversal to Southampton and was the pre-cursor for a difficult period in the club’s history, with big defeats at Blackpool, Crystal Palace and Leicester following this season.

However, Town are made of sterner stuff these days and a repeat of such a drubbing is unlikely, despite Posh boss Darren Ferguson suggesting Ipswich represented an opportunity for his side to take three points.

Speaking after the draw at home to Charlton and ahead of tomorrow’s encounter, Ferguson said: “No disrespect to the teams we were facing, but I fancied six points from these two home games this week.”

Carlos Edwards could return for the Blues after missing Tuesday night’s defeat at Nottingham Forest with a groin problem.

If fit, he could fill in for the suspended Richard Stearman, although Elliott Hewitt and Reece Brown are pushing for their first Town starts.

With Lee Martin also suspended, Murphy is likely to drop into midfield with David McGoldrick back in the fold.

Jay Tabb, who is joining on loan from Reading for a month, is likely to be in Mick McCarthy’s squad.

McCarthy can name five domestic loanees in his matchday squad.
