Leyton Orient manager Russell Slade hailed striker Ryan Brunt after the Stoke loanee climbed off the bench to secure a 1-0 victory over Brentford.
Brunt's 75th-minute effort gave the O's their second win on the bounce and earned them local bragging rights.
The 19-year-old, on loan until January and making his third appearance from the bench for Orient, coolly slotted home having collected former Bees midfielder Martin Rowlands' pass 14 minutes after replacing Michael Symes. Slade said: "I'm really pleased for Ryan because he's not had too much time on the pitch but he's starting to develop and get used to us."
He added: "Nuge (coach Kevin Nugent) has done a lot of work with him as well, extra work in training and that's paying off. Lo and behold, he got the all-important goal for us."
After an uninspiring first half, both teams showed more enterprise after the interval and it was the visitors who initially created the better chances. Jonathan Douglas had a powerful free-kick tipped over the bar by Ryan Allsop, who then turned a shot from Jake Bidwell past the post.
Orient offered little until the second half and Slade admitted they may have frozen under the gaze of the television audience.
"It was a tough start for us and we were a bit edgy," he said. "I don't know whether that was because the TV cameras were here. It was a good Brentford side and so it should be given the amount of money they've paid to put it together.
"The key in the first half was to stay in the game and in the second half we got competitive and put in a good performance. The two centre-halves put in great performances and we defended really well and looked resolute at the back."
Bees boss Uwe Rosler put a positive spin on the outcome despite the defeat, saying: "When you press so much and are so dominant like we were, we have to take our chances. With the players we have, we should score more goals given the amount of chances we created.
"I think the whole team did extremely well throughout, they did well both individually and collectively and attitude and I think our supporters can be very proud. I was very proud of not only the guys who started but also the guys that came off the bench. Unfortunately although our performance was top-drawer, we didn't get the result."
