The on-loan Arsenal teenager was introduced as a 55th minute substitute at Molineux as Gianfranco Zola looked to shore up his defence following Paul Robinson’s controversial sending off.
But, in what was only his second appearance for the Club since making a January deadline day move from the Gunners, Bielik put in an assured and impressive display to help Blues hold out for a crucial victory.
"We knew before the game that we had to win and start taking points," said the 19-year-old Polish youth international.
"I thought we did really well from the first minute, and scoring two quick goals made it much easier for us.
"The red card changed everything. I came on but we couldn't play as we wanted and we just had to keep the ball away from our goal and I think we did a really good job.
"It will make us more confident now and we're looking forward to the next game."
Prior to joining Blues, Bielik had made just one senior competitive appearance for Arsenal, with the majority of his football in England coming in Under-23s games.
"It was a massive experience for me, I never expected that the Championship was like this," he said.
"In the youth teams with Arsenal it's not like here.
"I have played with boys, here you just fight with big lads, you could see that with every fight, every single jump for the ball - they are like warriors, big, massive, stronger than me - but that doesn't mean I am worse than them. I felt really good.
"They are not much, much stronger than me. It's good that I am tall, you have to think about it and be smart with your body position and reading of the game. If you are not stronger you have to be faster than them.
"But I think I am a really good player, I can play in the air and I think that's OK for me, I helped my team on Friday and I am really happy.
"I hope the gaffer trusts me and if he needs me he knows I am ready.
"It was my second game in the Championship and I want to play more, and I'm just waiting for my chance. I really love it."
