Kane did not find the back of the net in any of England’s group stage games and recorded just one shot on target.
It marks a disappointing return for the 27-year-old who won the 2018 FIFA World Cup golden boot and topped the goalscoring charts in the Premier League last season.
The Tottenham Hotspurs striker is however confident he will turn things around in the business stage of the competition.
"People are quick to change their mind, it wasn't too long ago when I won the Golden Boot and I was the best thing in the world," he said ahead of England’s round of 16 clash against Germany on Tuesday.
"People were raving about me, and that's why I've always said, as a footballer, you can't get too high or too low, you just have to have that neutral mode. Self-belief is a huge thing.
"I've always believed in myself. I could go 10, 15 games without scoring but give me a chance and I'd back myself to score it. I'm in a good place. Going into Tuesday night, physically, I'm in the best shape of the tournament so far, and that's what I kind of wanted going into this.
"I felt maybe in Russia [at the 2018 World Cup] I started on fire, scored loads of goals, then maybe didn't have my best performances in the most important games, the quarters and the semi-finals.
"So, coming into this, physically, I wanted to make sure I was peaking at the right time and obviously we won't know until Tuesday night if that's the case, but that's the way I feel it's going."
