Five Key Dates In The Mesut Özil Saga
Jeers and whistles
Özil and Gündogan were jeered and whistled by travelling German fans during a 2-1 friendly defeat away to Austria in Klagenfurt on June 2nd, despite Özil scoring the opening goal.
Özil sat out the narrow friendly win over Saudi Arabia six days later in Leverkusen, but Gündogan was booed when he came on and reportedly later wept in the German dressing room.
Former Germany captain Lothar Matthaeus said Özil no longer seemed comfortable playing in the Germany shirt in the wake of the shock 1-0 defeat to Mexico in the opening World Cup game.
Löw then dropped Özil for the last-gasp 2-1 win over Sweden, but reinstated him for the 2-0 defeat to South Korea which saw the holders crash out in the group stages.
In an interview on July 6th in newspaper Welt, Germany's team director Oliver Bierhoff implied Özil should have been left out of the World Cup squad - then back-tracked in an embarrassing twist.
Two days later, Grindel says Özil should make his position clear to German fans in magazine Kicker, while Özil's father rejected the criticism and says his son should retire from Germany duty.
After scoring 23 goals in 92 matches for Germany, Özil retired from international football with immediate effect on July 22th after breaking his silence in lengthy posts on Twitter and Instagram.
"For me, having a picture with President Erdogan wasn't about politics or elections, it was about me respecting the highest office of my family's country," he wrote.
"The treatment I have received from the DFB and many others makes me no longer want to wear the German national team shirt.
"I feel unwanted and think what I have achieved since my international debut in 2009 has been forgotten.
"In the eyes of Grindel and his supporters, I am German when we win but I am an immigrant when we lose."
