Madueke was also named man-of-the-match by UEFA's technical panel afterwards.
The England international later said: "The first one was really nice, the second one was a tap-in, but that first one was sweet so I'm really happy.
"The bare minimum I need to give to my team is threat; they need to give the ball and feel that something can happen. Trying to score and be as decisive as possible is the next level I need to get to. I want to be consistently decisive for my club and my country. I think I can reach that level, so I'll keep working every day.
"We're tight, we want each other to do well. We have top players everywhere in the squad. It's about all of us a collective, not any individual. We know we all have a part to play, so that's a good thing about this team."
Madueke added, "I feel like we can win this competition, I feel like we can win the league as well. That has to be our aim. We're in a good place at the moment, so we'll just keep going."
