New Charlton boss Michael Appleton is happy for Brennan Johnson over his move to Tottenham.
Johnson played for Appleton at Lincoln City while on-loan from Nottingham Forest.
Appleton said: "It's one thing having pace, but it is another thing knowing how to use it.
"When Brennan gets the ball, he always looks to turn and get forward. He never really passes up responsibility.
"A lot of young players now want everything to feet - not enough are prepared to run in behind, but Brennan was prepared to do that, which I liked.
"I think I played Brennan in six positions. He just got on with it and was very comfortable.
"I think he will naturally end up as more of a number nine because he is prepared to run without the ball and, if he does that in more central areas, he will probably get even more goals."
