Sutton's predictions: Port Vale v Sunderland

No-one can tell me that Vale Park is an easy place to go because when I took my Lincoln City side there in 2010, we were 3-0 down inside 15 minutes and Vale had missed a penalty by then as well. Port Vale have done brilliantly to get this far, because they are having a terrible time of it in League One. Lincoln have already beaten them this season, probably because I'm not their manager anymore.
