Grayson: PNE should have been out of sight against Birmingham
Callum Robinson's early goal was all the Lilywhites had to show for a dominant first 45 minutes.
They were pegged back almost immediately after the interval by Che Adams' sweet strike, Grayson's men then overcoming a sticky spell before Jordan Hugill grabbed the winner on 78 minutes.

"Ultimately we've won but I was frustrated a little bit at half-time like everyone in the stadium.
"We totally dominated from start to finish, created some really good chances and had some outstanding individual performances.
"We just needed a couple of extra goals because you always know when you don't take those chances that the opposition are going to have a spell in the game.
"Ultimately we've showed a lot of character in the second half to stay in the game and dig in and and we took the chances when they came along."
