The 23-year-old Frenchman is Leeds' top scorer hit season - with seven in all competitions and five in the league.
But the striker knows both he and the team must score more goals, especially after losing to Blackburn Rovers despite leading 1-0 for the majority of the match last week.
"For me, it was a good game but we didn't get the three points - so it's a bad performance for the squad. But we are focused on the next game now against Derby, hopefully we'll win it," Doukara told LUTV.
"If you watch the game, we were in control of the game. They were not dangerous. But you have to stay focused all game - when you're winning 1-0, you aren't sure of the win."
The implication is that Leeds would have to go further than being 1-0 up - by scoring more. And Doukara's sentiments echo boss Neil Redfearn's warning that the Yorkshire side 'can't keep leaving games early.'

Leeds have scored just 21 goals in 18 Championship games this season - and they host the joint-top scoring side in the division at Elland Road this weekend.
As Opta stats show, Derby have netted 35 times so far this season. With 14 less, Doukara and his team-mates need to find their shooting boots a little more often.
