Germany midfielder Ilkay Gundogan will miss Euro 2016 after suffering a dislocated kneecap in training with Borussia Dortmund, his club announced on Friday.

“Season — and European Championship — finished!…Get well soon, Illy,” said Dortmund on their official twitter feed, revealing the news of the serious injury suffered by the 25-year-old.

The former Nuremberg player has been capped 16 times by Germany but already missed his country’s triumph at the 2014 World Cup because of a long-term back injury.

He previously went to Euro 2012 but did not feature at all during the tournament.
