PNE boss Simon Grayson believes all three Manchester United goals were ‘contentious’ as the Premier League heavyweights dumped his League One side out of the FA Cup.
North End wing-back Scott Laird opened the scoring at Deepdale in the 48th minute but United fought back to seal a 3-1 fifth round victory with three controversial goals.
Ander Herrera equalised for Louis van Gaal’s side and Marouane Fellaini added a second soon after.
Wayne Rooney won and converted a penalty after PNE keeper Thorsten Stuckmann allegedly fouled the England striker in the box.
But Grayson said Stuckmann never touched Rooney.
He said: “When you look at their goals, all were slightly contentious.
“For the first goal, it was in that grey area when it comes to the offside rule.
“Wayne Rooney wasn’t directly in front of Thorsten Stuckmann but was just to the side - sometimes you get them, sometimes you don’t.
“For the second, Tom Clarke was pushed slightly by Fellaini when the cross came over.
“Then for the third, Rooney was not touched by the goalkeeper.
“Yes, he had to jump out of the way because Stucki came sliding out but he didn’t touch him.
“All three goals could have worked out differently but that is the fine margins in football matches.”
