They were thrashed 5-1 at home by Arsenal and have now conceded 21 league goals this season.
They caused the Gunners problems in the first half but Arsenal unlocked them almost at will in the second period.
“My observation is mixed,” Whites boss Jokanovic said.
“We played the first 45 minutes well, created chances and gave them questions. But the second half they scored very easy goals. We opened all the doors.
“We’re showing so many weaknesses for the level we are at at the moment, defensively. We need to improve quickly on this.
“I believe my team tried. After they scored a second, I tried to find some way to equalise the game.
“We finished the game with 21 shots, and the other team nine. But they showed the quality, the pace, the strength too.”
