Bundesliga: BVB fears Konstantelias will tear his cruciate ligament

Ole Book had previously made similar statements. “Of course we should be a little bit careful today about what we communicate. But we are definitely worried about a serious injury,” said Sky’s sports director.

Kovac: “Really very sad”

Konstantelias was substituted due to injury in the second half of the win against HSV and was left holding his knee. The 23-year-old Greek had previously played well and scored Dortmund’s second goal. Kovac said he was “really very sad” because of the feared serious injury. “We have already seen how important he can be and is,” he said.

Book explained: “At first I felt incredibly sorry for the boy because he arrived here and has had a great presence in the dressing room from day one and has also brought an impact on the field. I think we all really like him.”
