The full-back is one of five Spurs players who now look set to be part of Roy Hodgson's final 23 for the tournament.
Kyle, Dele Alli, Eric Dier, Harry Kane and Danny Rose all started England's friendly against Turkey last weekend and will be ready again for this evening's friendly against Australia at Sunderland's Stadium of Light (7.45pm).
The squad will be trimmed from 26 to 23 on Tuesday. England's final friendly is against Portugal at Wembley on Thursday and first match in Euro 16 against Russia in Marseille on June 11.
Kyle admitted himself that he reached top form again in 2015-16 after a difficult couple of seasons through injury - and a lot of credit for that must go to Kieran, who has pushed him every step of the way.
Kieran joined us from Burnley last summer and made 19 appearances in all competitions, including starting all 10 matches in the Europa League.
He recognises that Kyle's form is the reason he made only five starts in the Premier League.
"I knew it would be difficult competing with Kyle and he’s been brilliant," reflected ever-honest Kieran. "We’re good mates and we wanted to drive each other on. We can only try to make each other better players and we have that competition throughout the squad.
"Kyle deserves to be in the England squad, he’s done well and kept me out of the team for most of the season. There’s nothing I can do about that apart from continuing to work hard in training.
"Full credit to him and hopefully he’ll do well in the summer."
