Reds Head Coach Lee Johnson caught up with the press after his side booked their place in the second round of the Johnstone's Paint Trophy.
"Generally, they're (Scunthorpe) a good side and full of strong, experienced professionals. At times they couldn't live with us.
"It was nice because we didn't have to expend maximum energy. We managed to keep the ball moving. I thought Kadeem Harris was a really good outlet for us and was a threat all game.
"This group will get better and as we go into Saturday, I hope we'll see more of what we're about."
Lewin Nyatanga and Marley Watkins got the goals in the second half to secure a 2-1 win for the Reds.
"He keeps going, Marley," continued Johnson. "He never stops running. He got a bit lucky but the more he works the luckier he gets.
"Again, I'm pleased with his performance because I think we've played more minutes than anyone in the country. It's important we looks after them because we've got a humongous game on Saturday.
"Progress means a lot in this competition. We've got a good squad and we can utilise that. We've got Ryan Williams coming back so, hopefully, we can utilise him. We've brought in Michael Smith today and all of a sudden, you're looking round and not sure of what team we're going to pick."
