Leeds United boss Marcelo Bielsa had mixed emotions after their 4-3 victory over Fulham.
Bielsa admits they need to improve at the back.
He said, "This won't be a constant all year. It is very difficult to maintain the efficiency [in front of goal] we have had in these first two games.
"The characteristics of our game is to create goalscoring opportunities. In these two games we have created very little but we have scored all our chances.
"We have had two very different games. Against Liverpool we tried to get close to a very big rival and today we tried to not be caught by Fulham. Both were very difficult games."
