Barnsley boss Simon Davey was upset with the referee after he awarded a controversial late penalty which ensured the relegation-threatened Tykes had to settle for a point from a 1-1 draw at Coventry City.
Davey even suggested the official, Stephen Cook, was too inexperienced to take charge of such an important match.
He said after the draw: "I tried to knock on the referee's door after the game but he was having the longest shower I've ever known in my life. I think the linesman is rubbing his back.
"I was told after the game that it was only his second Championship game which, when you look at it in hindsight, considering the importance of the fixture, especially for us, you'd expect a more experienced referee. But that's not for me to decide.
"What the FA should look at is the teams fighting for their lives. They should appoint somebody for those matches who's got some experience and a wise head.
"You want somebody who makes the right decision 95 per cent of the time and not 60 per cent of the time.
"It's not an apprenticeship. That's what's been difficult to take over the season to be honest."
