Jamaal Lascelles clumsily fell against the Spurs frontman in the area and appeared to bring Kane down – but referee Mike Dean did not point at the spot, and the VAR control room agreed with the man in the middle.
Kane, speaking to Sky Sports, is adamant the officials got it wrong – although he remains an advocate of the use of video technology.
"It is hard to understand how it hasn't been given," he said.
"I kind of tripped over his (Lascelles) arm and then his body. Whether it was deliberate or not, from my point of view it is hard to take. It is there to help the referee on the pitch. That being said he didn't know, he couldn't see.

"That's where VAR is there to help him out. If he had said 'no penalty' and the VAR said it was a 50-50, you can agree.
"I don't know what the conversation was - whether he said he didn't see it or not, but from my point of view, it's hard to understand. That's the way football goes sometimes.
"Sometimes you are going to get the rub of the green with VAR, sometimes not. I felt it didn't go our way against Newcastle.
"It is the 50-50 ones that are always going to be hard. They are never going to take away speculation because like against Newcastle, it is always a matter of opinion.”
