Norwich City boss Paul Lambert has welcomed reports linking members of his side to the international scene.
Lambert told BBC Radio Norfolk: "If they're getting talked about it's great for them as individuals and great for the football club.
"It's brilliant for them and the way they've started the season."
Midfielder Johnson, 24, started his career in non-league but has impressed during Norwich's solid start to the Premier League season, so much so he is said to be on England boss Fabio Capello's radar.
And 26-year-old Tierney, who was playing in League One with Colchester in January, has caught the eye with his performances at left-back.
"That will come with the territory of playing well and hopefully the lads will keep their heads," said Tierney, who has been the Canaries' only ever present in the Premier League this term.
"I know Johnson's been linked, Wes Hoolahan [to Ireland] too, there's quite a few of us, we'll just keep our heads down and working hard for the club.
"I think it shows people are taking Norwich City seriously now, we're doing well, we're playing good football. People are realising we're quite a force in this league."
Meanwhile, Lambert has admitted the international break has come at a good time for his side, who sit ninth in the table after seven games.
"So they deserve a break and we'll come out a week on Saturday against Swansea and hopefully win that."
