Sheffield Wednesday boss Carlos Carvalhal said there were three major reasons why Sheffield Wednesday's winning run came to an end against Brentford.
The Owls' victorious four-game streak was halted by the Bees, who came away from Hillsborough with a 2-1 win on a night not short on controversy.
John Egan put Brentford ahead and Harlee Dean doubled the advantage before the break to leave the Owls chasing the game in the second half but this came after Fernando Forestieri had been denied a penalty when bundled to the ground by Dean.
That was just moments before Dean Smith's side opened the scoring and it proved to be a pivotal point in proceedings.
Wednesday spent the majority of the second half in Brentford's half with visiting goalkeeper Daniel Bentley thwarting them on a number of occasions and Forestieri did pull one back very late on but it proved to be too late for Wednesday to snatch a point.
Speaking after the defeat, Wednesday's first since losing to Brighton a month ago, Carvalhal focused on three aspects which he felt were crucial to the result.
Firstly, the performance of referee Darren Bond - 'a disaster in the first half'; his own side's display - 'too slow to start' and that of Bees keeper Bentley - 'fantastic'.
"Three important points in this game," began Carvalhal. "First, the referee in the first half was a disaster in my opinion. He made everybody nervous. He made the crowd nervous, my players nervous he made me nervous. He didn't see a clear penalty. He saw a fault that achieved the first goal, very similar to the penalty, two minutes later. He didn't see the block they did on Sasso for the second goal.
"More than this, not just these critical situations, there were a lot of faults, little things that made everybody nervous."
Carvalhal added: "The second point, we played very predictable in the first half. We played three days ago, Brentford didn't play. We started very slowly. I think about the three days between the games, it was probably about that but we must do better in the future.
"The third part, in the second half, the Brentford goalkeeper was fantastic. He made fantastic saves. We spoke with the players at the break that we can turn this game. We must play with a big heart. I know you are tired, jump the red line, do the 45 minutes like we are doing the last 45 minutes of your life. They were fantastic.
"We created a lot of chances to score but we didn't achieve the goals."
The defeat keeps Wednesday in sixth place, level on points with Leeds united in fifth with the sides due to meet in a huge Yorkshire derby at Elland Road on Saturday. Norwich City, in seventh, are seven points behind Carvalhal's side.
