The 24-year old has emerged as a Three Lions wildcard with impressive displays in the Premier League for the Canaries this season but he says that he is solely focused on performing at club level rather than thinking about a national team berth.
"It's a great achievement for me to be watched by the England staff," said Johnson.
"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," he added.
"If I get a call-up then great, that's a bonus to me."
