Kane did not score a goal against United, but was a bother for the defence, playing a role in the opener.
Ferdinand heaped praise on the premier league’s leading scorer and was impressed with his link up play.
“I think Kane showed today why he’s the best striker in the league and one of the most potent in Europe because he’s bullied United’s centre halves,” Ferdinand told BT Sport.
“He totally dominated them physically and brought other people into play. The contrast between him and Lukaku today was so evident it was unbelievable from up here where we watched it.
“The ball going into him, sticking, holding centre halves off and bringing others into the game. That’s a real No. 9. That’s what you want to see a No. 9 do.”
