The 19 year-old told City's website: "I thought it went really well. It was my first game for the first team and I loved every minute of it. I thought I did alright as well.
"It's good for me to be there playing football with the big boys now. That's what my aim was and what I'd said the last time I did an interview for the website - to be up there and play with the big boys, and I've done that. I've just got to keep working hard now.
"I'm so proud. I'm a professional footballer now - that's always been my dream. I've played on live television, in front of a big crowd; it's unbelievable."
The Swede said: "He's extremely quick, has good feet and although he's not that tall he's very brave in the tackle. He's also good in the air, so his all-round game is important to us. It's hard to make comparisons, but he does remind me a little bit of Ashley Cole a few years back, on the other side of the pitch."
