B Team Head Coach Kevin O'Connor was unhappy with the way his team performed in their 3-0 defeat to Queens Park Rangers at Griffin Park on Tuesday night.
The former pro, with over 500 appearances in a Brentford shirt to his name, told iFollow that his team weren't up to the challenge that the opposition presented them with.
"I'm very disappointed," said Kevin. "I thought we didn't really turn up tonght, it was an opportunity for our boys and I think it got to them. It got to most of them unfortunately and we didn't play the way we have been playing so it was disappointing.
"We had the opportunities, just tonight it didn't go in. Am I surprised? No because we still created the chances so it was one of those days where we hit the bar and had a couple of chances we haven't taken. It's just disappointing we haven't scored as well."
Asked about the lessons his team could take from the defeat, Kevin said: "I think it's our reactions. Once we go a goal down, we came into again at the start of the second half and then concede the second. After that, our heads dropped and I never felt like we were going to get back into the game.
"That was a big disappointment for me, which I told the players in the changing room, we have to learn from that. Even if we do go two down, of course we can get back into the game, so we have to be more positive mentally when that happens."
First Team players Luke Daniels and Sergi Canos dropped into the side for some game time and Kevin was glad to have their influence on and off the pitch.
"It was good," said Kevin. "Obviously you can see how they prepare, they were the first in the meeting, and also how they warm up. It's good for our boys to see that. Luke spoke after the game as well about how disappointed he was in conceding goals, and that should be the same for absolutely everyone.
"I thought Sergi was good, he showed us his quality going forward, and hopefully he can take that into the First Team. It was good to have them around the team but hopefully now they can go and play for the First Team."
Herson Rodrigues Alves was named captain of the B Team for the first time, Kevin explained his choice of skipper.
"He leads on the pitch and off it," said Kevin. "The way he acts, the way he is around the boys. He looks after the younger boys and he's a positive presence and influence on the squad, so I thought he deserved that tonight. Unfortunately for him it's ended in a defeat but he fully deserved to be captain tonight."
The squad head off to Germany on Friday morning for a five-day stay and two fixtures against European opposition. Kevin is looking forward to getting back to action again.
"We have a couple more days at the training ground first, where we need to get some lessons into the boys. We go out there looking to up our performance and get back to the way we have been playing."
