Tottenham striker Harry Kane admits his form hasn't been good enough since the start of the season.

Kane was substituted as England captain for last night's World Cup qualifying draw with Hungary.

"It's natural that people think like that, people are entitled to their opinion," Kane told ITV in response to criticism of the start to his season.

"At the end of the day I'm my own biggest critic and put pressure on me to perform. Everyone who knows me knows I'm confident whenever I'm play.

"I'm as clear as anything, a lot of noise around me, when you're a high level sportsman you could expect that.

"Performances for club and country maybe haven't been there last few weeks but I'm confident in my ability – sometimes that's just the way it goes."
