The Frenchman was kept out of the team last season due to injury, but he has enjoyed an extended stay in the Spurs side under Tim Sherwood after finally reaching full fitness earlier in the year.
"When you are injured, you have to work by yourself and it is just a nightmare," Kaboul told reporters.
"Finally now I feel like I am coming back to my best. I'm not there yet, but I am trying. I wish we still had ten games left to play this season, but unfortunately we only have five left.
"I am feeling much better and I'm going to work again this summer to come back even better and have a good season next time."
Kaboul is likely to be involved when Spurs host Fulham at White Hart Lane on Saturday afternoon.
