Having lost 1-0 at Derby in the first leg, Sessegnon levelled things on aggregate at Craven Cottage before Denis Odei header a second to earn Fulham victory in the tie.
And the Fulham boss said: "I'm not Santa Claus, I am a football coach, and I don't give any of my players presents". "I see so many words in the newspapers, the media, talking about him but he has both feet on the ground".
The 17 year-old provided the telling assist 19 minutes later, bending a corner onto the head of Odoi, who glanced the ball over Carson and into the left-hand corner of the net to keep Fulham's promotion hopes alive for one more match.
After a plethora of first-half chances went by the wayside, Sessegnon broke the deadlock in the 47th minute when he lashed home from close range and then set up Odoi with an in-swinging corner. I like to play my normal game and I don't let other people bother me. If the play-off final goes to extra-time then it will nearly be clashing with that game in the Ukraine.
Fulham ended their play-off hoodoo in style by coming from behind to beat Derby 2-0 and put themselves one win away from the Premier League.
Gary Rowett accepts his side found it hard to contain Fulham in the second leg.
"This club needs this kind of happiness", said Jokanovic, "After 43 years we will play at Wembley and it is an important achievement for us".
'I can't complain because Fulham created enough opportunities and you knew they would score at some point.
'You have to accept that Fulham were better in the second leg and had enough to get through'.
"Many times we have been close to brilliant, tonight we were close to flawless".
A major setback arrived when Sessegnon struck just two minutes after the break, and Rowett was disappointed with the quality of both goals that his side conceded.
