Midfielder Sam Field says the excellent atmosphere around the team was on display at Brighton & Hove Albion, as Albion battled to a 0-0 draw.
Playing in the heart of the Baggies midfield, Sam was one of nine changes made by Darren Moore for the Emirates FA Cup tie on the south coast, with four Academy graduates starting the game and Rayhaan Tulloch, 18, coming on for his senior debut.
While many young players would have shied away from the occasion, Sam felt Albion's youthful side played with a unity which helped them to impress.
"There's a great bond at the Club," said Sam.
"We just all get along really well and want the best for each other.
"Just because some of the lads haven't been playing in the league doesn't mean they're not good.
"None of us were thinking we were going to be weak here at all, we were looking forward to it and we all trusted each other, which I think quite clearly showed on the pitch."
Field was joined in midfield by two fellow Academy graduates, Rekeem Harper and Kyle Edwards.
Sam urged his young team-mates to go out and excite Moore, and he was pleased with their performances.
"I'm used to playing with those two lads on Sunday mornings and it's a big change from that with 27,000 here," added Sam.
"I said before the game 'let's just show the gaffer how mature we are' and I think we did.
"You learn of the likes of (Gareth) Barry, (Chris) Brunt, Jake (Livermore) and Mozza.
"It's brilliant for us to watch them and, when we get our chance when we step in, we just want to do it well.
"And to have five Academy graduates on, I'm sure Mark Harrison (Academy manager) and all the staff will be over the moon with that, we owe a lot to him."
Despite an intense fixture list ahead in the Sky Bet Championship, Sam insists Albion want to be involved in the FA Cup to build further confidence at the Club.
"I'd love a cup run," he added.
"It's a chance for me to get game time so I'm desperate for it, and all the lads out there were desperate as well, the main thing was to show them what we can do and I think we did.
"They had some chances but we could have easily snatched something at the end so we'd love a cup run.
"The Championship is a lot of games and it will be the priority but cup runs just build momentum and playing like that I'm sure we can cause a lot of teams a lot of problems."
