Posh travel to the Cardiff City Stadium on Saturday to face in the in-form Bluebirds (3pm).
Peterborough United travel to the Cardiff City Stadium in the npower Championship on Saturday to visit the home of one of the division's in-form teams (3pm).
The Bluebirds have an excellent record in front of their own supporters with 10 victories in a row, while Darren Ferguson's men have chalked up two away wins this season at Hull City and Barnsley.
Ferguson knows that nobody outside of the building will expect anything other than a Cardiff City victory, but he told the press on Thursday, that he believes his players can cause an upset against Malky Mackay's men.
'They’ve got to get beat sometime, it might be one of those games that changes our season, no one expects us to win, it’s bottom against top a team going very, very well, it might just be one of those days. I’ve seen it many times in this league in particular that anyone can beat anyone and we know on our day we can do that.
'I saw them play against Blackburn on Friday and it was the best performance I’ve seen from any team this season they were magnificent and we’ll have to work with their energies and their work ethic.
'I took a lot of positives from our performance against Middlesbrough and from our last away game against Charlton as well so hopefully we can take that form into it.
'We’ll go there and play the same way, we’ll go and try to win the game and I think with the four they’ve got up and you give them easy possession it might only be a matter of time so we’ll go there and try and have an effect on the game.
'I thought Saturday we were a lot more like ourselves attacking wise and the Charlton game to be fair and I think we need to be like that, we’ve got a lot of creative players in our team, obviously we’ve got to have the right balance in terms of we’ve got to be able to defend better, so we’ll go there to win the game,' Ferguson said.
The Posh boss is without the services of front man Saido Berahino who has a knee injury, while Kgosi Ntlhe and Peter Grant are long-term absentees. Tyrone Barnett has returned to London Road after picking up a knee injury in a behind closed doors fixture for Ipswich against the Nike Academy on Monday. He is expected to be out for three months.
