The England international has been in impressive form this season for Andre Villas-Boas's side.
Freund singled Lennon out for praise following his efforts in the 1-1 draw with Manchester United and insisted that the former Leeds United man has always had the talent to be one of the best in the game.
Freund told the Daily Star: "For me as a coach, it's great to see Aaron at that level.
"We created 10 chances against United and he was involved in seven. That means that we have one of the best wingers in England.
"What I can say is that Aaron has always had the talent to be one of the best wingers and now he is playing well every game."
Lennon joined Spurs from Leeds in 2005.
