The 24-year-old left it late at Wembley - scoring in stoppage time - but he was unconcerned by the nature of England’s progression.
“[Qualification] is all that matters,” Kane told ITV. “It was frustrating at times and we had to be patient.
“In the last 10 minutes, they were getting tired and we created a few opportunities - I was happy to finally put one in the back of the net at the end.
“It’s amazing to get there. It’s no easy feat these days [to qualify]. There’s a lot of top countries around the world struggling to qualify. We’re all delighted.
“That’s job done for us. We have another game on Sunday [against Lithuania] and we need to keep doing what we’re doing and working hard.”
Gareth Southgate’s side will round out their qualifying cycle with a final match away to Lithuania on Sunday.
