But they defended heroically to end the club's four-year exile from the Premier League.
That figure could rise to in excess of 280 million pounds ($538 million) if the club from southwest London survives its first season back in the Premier League.
And Khan was celebrating from the stands of what could soon be his personal property as he negotiates a deal to buy the iconic stadium from the Football Association.
Another player linked with a move away from the club, Cairney scored the all-important goal to send Fulham back into the Premier League, leading by example.
Redundancies for key staff and cost cutting are now likely to be on the agenda at Villa after their Wembley failure, while Fulham can fund the rebuilding of their Craven Cottage home with the cash that will roll in from their Premier League elevation.
Lacking a focal point in their team with Ireland striker Scott Hogan left on the bench, Villa's attempts to grind out a win against a more energetic and youthful Fulham side had come up horribly in what was a limp first half display from Steve Bruce's side.
Dominating possession for long periods, Fulham were the more adventurous side.
But Fulham managed to contain Villa and burst into life two minutes after Aboubakar Kamara's deft touch and looped effort went over the bar.
Captain Cairney will claim the plaudits for scoring the winning goal but Fulham's 18-year-old sensation Ryan Sessegnon was very much the architect. "But football won today", declared match victor Cairney.
The talented Sessegnon was looking to increase the lead but the Manchester United and Chelsea target headed straight at Johnstone following a cross on 33 minutes.
Villa pushed hard for an equaliser in the second half and Fulham goalkeeper Marcus Bettinelli prevented Jack Grealish from netting a superb solo effort.
Odoi missed the ball and instead wiped out Grealish, collecting a second booking to leave Fulham a man light.
But Villa lacked the cutting edge to take advantage and Jokanovic's men were soon celebrating their return to the big time.
