They came from behind at the weekend to beat Middlesbrough 2-1, a win which saw a change of shape for North End boss Ryan Lowe.
Switching from his usual 3-5-2 formation, Lowe instead opted for a 4-3-3 and it proved successful.
Will he keep with that shape for the visit of the Swans, who also like to play 4-3-3, or will be a return to the usual for the Lilywhites?

Although he was replaced against Boro, it was due to being booked and he has not yet started from the bench in a game during Ryan Lowe's tenure. Photo: CameraSport - Dave Howarth

8. CM: Ali McCann
On of the more consistent midfielders so far this season, McCann's fine work off the ball could see him included against a side who like to keep the ball. Photo: CameraSport -
