Werder Bremen coach Thomas Schaaf still found room for complaint after his side's excellent 3-1 UEFA Cup defeat of Udinese.
The German side were seemingly cruising towards the semi-finals after taking a 3-0 lead in the last eight, first leg encounter only to concede a goal to Fabio Quagliarella in the 87th minute which gives the Italians some hope.
"It was a totally unnecessary goal," said Schaaf. "We were not just nonchalant, we were sloppy.
"But at the end of the day, we have only played one game and now have to be fully concentrated for the second game. The positive we can take from conceding the goal is that we will have to be awake."
The result could easily have been worse with Quagliarella missing a hat-trick of good chances while Bremen were clinical in front of goal, taking each opportunity which came their way.
And Schaaf knows his side must improve if they are to reach the last four of the competition.
"The opponent was in front of our goal relatively often and we should have prevented that," he said. "But on the other hand, we did also score three goals."
Bremen were inspired by Brazilian playmaker Diego, who scored twice with Hugo Almeida adding a third.
