"I can remember a game very similar when I was at Watford and we played Sheffield United," said Boothroyd to the Press Association. "Sheffield United were very experienced, had Neil Warnock, had been up and around the Championship for a long time. We were green and naive, just coming together. 
"We went 2-0 up and got all excited with ourselves and we lost 3-2, it was a massive, massive lesson about understanding professionalism. I`ll be very careful how I say this, Neil Warnock and his teams are masters at influence and we got a lesson that day, and we did again on Tuesday night I think.
"We weren`t influential enough on the game, on officials, we were too respectful and we have to learn quick because you get punished in this league.
"We`ll start by showing clips of the video and discussing how we watch the game rather than partaking in it."
