Stuttgart could well be without influential winger Alexander Hleb when they open their Champions League season against Rangers on Wednesday. The Belarusian is struggling with a thigh injury sustained against Hamburg at the weekend. "We have to wait and see whether he still has a lot of pain on Wednesday. It will be a close call, but we will find a solution to Hleb's injury trouble," coach Markus Babbel told Bild. Meanwhile, Stuttgart are set to miss Swiss full-back Ludovic Magnin, who suffered a thigh tear in training.
