The Congo international was a peripheral figure at the start of the season but has been a regular since returning from the Africa Cup of Nations.
And Jokanovic has been delighted with how the 25-year-old has adapted himself to English football.
He said: “Neeskens Kebano had a few months to get to the level we expect and he's a player who arrived from a different culture. He needed time to adapt himself.
“I used Floyd Ayite and Lucas Piazon in his position and they did a fantastic job. He was working with passion and was fighting for a space in the starting XI.
“He pushed hard to fight for the space and in the last month and a half, he's been a key player.
“He's scored many goals and I expect he'll be at the same level and I expect some people out of the squad will push harder to provide the highest competition.”
