Kane was controversially awarded a foul in a challenge with Adam Lallana, with BT Sport pundit Martin Keown going as far as saying that the striker's intention was "dangerous" and that a decision should have been given the other way.
"Harry Kane was in a position to control the ball and Lallana came in a reckless fashion," Mourinho said. "Why are you saying it is clever? Clever is taking the ball and scoring a goal. It's a foul.
"I thought it was a direct free-kick but VAR said it was inside the box because it was on the line. What are we talking about being clever? Harry Kane just wants to score goals.
