He said: "When you have the number nine that you know is going to play week in and week out and is going to score 20-plus goals, it helps a lot.
"Sometimes, there is part of the games that we can plan and make decisions, the coaches and how we defend, how deep, how high, blah, blah, blah. But to put it on the net, it's normally only one guy. That guy is the number nine.
"You know what I would like? And this is like a message to all the offensive players. Grab the number nine shirt for you and make yourself the number nine of Tottenham.
"Really, show it, you know, score goals. Get yourself in a position that everybody knows when you play Tottenham number nine is this guy. And that would be an extra motivation for all the offensive players."
