Matt Smith's departure made it essential for the Whites to sign the speedy 26-year-old striker, and Jokanovic was pleased to add the Ivory Coast international to his squad.
That said, deadline day was a case of what might have been for Fulham as they missed out on other targets.
Jokanovic said: “I was expecting more, but it's logical if I decide to let Matt Smith leave and send Cauley Woodrow and Stevie Humphrys on loan.
“The minimum we can do is bring in a player who can cover this position. He's yet to train with us but I expect he can help us in the last 18 games. I expect his main strengths to be scoring goals.
Jokanovic was critical of Fulham's recruitment strategy in the summer but opted to retain a dignified silence when asked for his views on their January work.
He added: “I don't want to talk about recruitment. I'm proud of the people working with us. The two new players can help us in this period in front of us.
“It's a credit for the people who played today, on the bench and in the stand. This squad will try and take important steps.”
