Sheffield United boss Chris Wilder talking to BBC Sport: "I'm involved now in a different sport, it's a new game to where I started as a 16-year-old. It's a different game. It's a completely different game and I've got to get my head around that.
"We were told at the start of the season that the linesman would keep his flag down, but he didn't. The referee was about to blow his whistle but he didn't. You can criticise my players for stopping, but even the goalscorer didn't look too interested. It's disappointing. It sucked the life out of the whole stadium. We're on the end of a poor one. The game has changed and it's quite sad.
"The players are disappointed. You're talking about a manager learning a new game but the players have to learn on the job too. It seems to be all over the place at the moment.
"It just doesn't feel good. It doesn't feel good to be involved in. It doesn't feel good when you score a goal. I can handle it if people make a mistake, we talk about it all evening out, but it's just taken a completely different feel.
"We'll get told it's new, we're all learning about it. I'm not sure I want to learn about it, I'm a bit fed up of it. It's a mistake by the linesman, why didn't he just keep his flag down? Five minutes later it happened twice and the referee blew up twice. What's the difference? Where's the consistency we're all after."
