Toni Kroos suffered a groin injury in the first half of Bayern Munich's match with Juventus in the Champions League quarterfinal and was substituted after only fifteen minutes. The midfielder was replaced by Arjen Robben.
After David Alaba's opening goal, Juve had turned up the pressure and were in firm control of the match for about ten minute stretch. Robben's presence on the field acted as a release valve for the pressure that was building. His ability to get down the line and behind the Juve defense was a big reason why Bayern turned the tables and controlled the last twenty five minutes of the first half.
The second half is just starting in Munich, so no word on the extent of Kroos' injury is known at this time. Once we receive an official word from Bayern regarding Kroos, we'll have it up as soon as possible. For now, let's keep our hopes that it's not too serious.
