While the 24-year-old could be in contention for a call-up to the senior squad after his impressive form at Carrow Road, the playmaker has insisted that he is focused on the Premier League.
"It's a great achievement for me to be watched by the England staff," Johnson told BBC Radio Norfolk. "But I'm just concentrating on doing my best for Norwich City.
"I've just got to keep my performances up and see where that takes me. If I get a call-up then great, that's a bonus to me."
The midfielder joined the Canaries from Leeds United in the summer transfer window.
