Posh have been superb on the road this season, winning all five League One away games so far and scoring 17 goals. Home form is of far more concern as Saturdays 2-2 draw with Blackpool was a third game in a row withot a win at the ABAX Stadium.
We might have to tweak the way we play at home, Posh boss Steve Evans said. Teams sit back against us at our place and its been more difficult for us to create chances.
But Id be a fool to come up with a wacky game plan just because we are playing at Sunderland. We have been terrific away from home all season. Weve played some great football and scored some stunning goals and we will try and play the same way tomorrow. We will be positive and we will be looking to win.
Sunderland are a huge club at League One level. We know all about the history and the passion of a fantastic fanbase. They will be favourites which is unusual for us latel, but its 11 v 11 and I have a group of players who will not be intimidated by a big crowd or a big club.
There are lads in my dressing room who have played in front of 30,000 plus gates at Rangers and Celtic. They will be used to the atmosphere they will find tomorrow.
Posh should be at full strength. Ivan Toney, Jamie Walker and Ryan Tafazolli all finished Saturdays game with dead legs, but all were expected to train today.
There could be team changes for Posh with Joe Ward, Jason Cummings and Mark OHara all pushing for a start.
Sunderland will be without midfielder Lee Cattermole who is suspended, but former Wigan man Max Power will replace him.
Aaron Wilbraham put the hosts ahead early on but Portsmouth replied with goals from Jamal Lowe, Brett Pitman and Matt Clarke to maintain their unbeaten record in the league this season.
Kenny Jacketts side replaced Peterborough at the summit after Posh were held to a 2-2 draw at home by Blackpool. Doncaster climbed to third in the table after a 3-2 win at Plymouth, who remain rooted to the bottom.
