Jokanovic has said that he is still upbeat about the tie, despite the Cottagers having lost their last two games following a 23-match unbeaten streak.
"It's not a bad result, it's not the result we deserve, but it's part of football," the coach said. "We dominated and they scored after one cross and Jerome scored a fantastic goal.
"We cannot be frustrated, we must be in some way confident having showed the quality and a great mentality. What we want to do is change the story and win the game on Monday."
Fulham exited the promotion race at the same stage last season, losing over two legs to Reading.
