On signing he said "“I’m delighted. I’m glad to get it out the way early as well. I spoke with Stuart (Webber) and the boss (Daniel Farke) not so long after the season finished so it’s nice to get it sorted. There was a bit of interest (from other clubs) towards the end of the season and when Norwich came up, with the history of the club and what they’ve got going on with the boss and the players they’ve got here, I think it was a really good fit for me. It’s a massive step in my career which is why I had to make sure it’s the right decision for me. I didn’t want to rush into anything. I had a few offers but after speaking with Stuart and the boss and having a look around the training centre, I knew this was the place for me. I’m looking forward to getting fit and getting ready for pre-season. We’ve got about three weeks left so I’ll have a couple of days on holiday and then we’ll be back at it, ready to go.”

Farke said “I’m very pleased with this transfer because Kieran is full of potential. He’s a young player on his way up and has experience on the international stage. He’s young, homegrown and has proven that he can score goals and get assists, so he’s pretty versatile in all offensive positions. I think it’s a great addition to our squad. He caught my eye when he was on loan at Nottingham Forest with many goals and assists, never losing his way. We’re really pleased as there was a lot of competition for his signature. “It’s a really good transfer for us and I’m pleased that Stuart Webber was able to bring him in.”

Dowell made his competitive first team debut for Norwich in the Carabao (League) Cup first round clash at Luton on 5th September 2020 which Norwich lost 3-1.
