“I thought we started the second half well too but then in the 52nd minute the officials didn’t do their job. Billy Sharp was offside for the initial cross and then the ball was in Kali’s hands and he has gone in with his studs up, too.
“That was a real momentum changer and they are a tough team to play against and when you concede a third you think the game is going to drift away.
“You have to give them [United] credit for the way they defended but when Tyrone scores you could feel it in the stadium. The players had a bit of a sniff and them you get a comeback like that.
“But I can’t say I’ve never known a game like it because there was the Nottingham Forest one!”
