The France international picked up a knock during October’s international break to rule Kante out of six games in all competitions.
Chelsea suffered a surprise 2-1 loss to Crystal Palace without their defensive midfielder before battling to a 1-0 win at Bournemouth.
The Blues conceded six goals in two Champions League games with AS Roma as Antonio Conte’s side collected one point against the Serie A giants.
The Chelsea manager named Kante in his starting line-up for the visit of Manchester United at Stamford Bridge last weekend.
The former Leicester midfielder, alongside Tiemoue Bakayoko and Cesc Fabregas, managed to get the better of Jose Mourinho’s midfield.
Indeed, Kante’s performance gave Chelsea the platform to secure a 1-0 win against Manchester United thanks to Alvaro Morata’s 55th-minute winner.
Former Blues captain Desailly believes Kante can help to energise Chelsea ahead of their remaining 27 games in the Premier League.
“It is not a coincidence (that they won),” Desailly told Omnisport.
“I did not see the game, but my friends told me he had a great game.
“(Chelsea) were in need of a player who can sit in front of the defence to help and block the opponent and bring that extra energy, to play the intervals, to start the actions.
“I’m very pleased he’s back. Psychologically, it’s also a boost for the entire collective, because since he left, Chelsea have been on and off. Now, he’s back and he stimulates the rest of the group.
“They don’t have big individual players, but at least if collectively they are back to their original level of last year, then maybe Chelsea will be back at a certain level.”
Chelsea signed six players in the summer transfer window to bolster their squad ahead of a return to the Champions League.
Kante moved to the Blues in a £30m deal from 2016 Premier League champions Leicester City.
