The France international defender feels the 29-year-old striker can fire Spurs to a fourth-place finish in the Premier League
The striker found himself out of favour at White Hart Lane under former head coach Andre Villas-Boas, but has scored eight goals in 10 Premier League appearances since being welcomed back into the first-team squad by the Portuguese's successor.
Kaboul feels the Togo international has become a vital player for Tottenham and says that Spurs are more optimistic about their chances of pulling off top-four finish with Adebayor in such a rich vein of form.
"If you give confidence someone like Ade, he will repay you so much more," Kaboul told the London Evening Standard. "He will give you the best, and that is what is happening now.
"Every player can always do better, but he is performing very well and we need him.
"The thing with Emmanuel is that he has always been a top player. He has always been up there, and he is not someone I have ever seen as an average player."
Tottenham travel to Ukraine to face Dnipro in the Europa League on Thursday, before visiting Norwich City in the Premier League on Sunday.
