BERLIN: Germany captain Bastian Schweinsteiger on Friday announced his retirement from international duty with immediate effect.

The 31-year-old Manchester United midfielder, who won his 120th and final cap in Germany's 2-0 defeat to France in the semi-finals of Euro 2016, revealed the news on his official Twitter account.

He retires from die Mannschaft with his Old Trafford future in the balance having reportedly been told by United's new coach Jose Mourinho that he is one of nine players free to leave the club.

Schweinsteiger still has two years left to run on his United contract.

A knee injury in January flared up again in March, restricting him to just a handful of matches before he played at the European championships, netting a goal on his return against Ukraine in Germany's opening pool game.

The defensive midfielder said now was the right time to retire from the national team ahead of Germany's first qualifier for the 2018 World Cup against Norway on September 9, four days after a home friendly against Finland.

“I have just told the national head coach (Joachim Loew) to no longer consider me for selection in the future as I would like to retire,” wrote Schweinsteiger.

“I would like to thank the fans, the team, the German Football Association and the coaches.

“In 120 internationals, I have been allowed to run out for my country and experience moments which were undescribably beautiful and successful.”

Schweinsteiger's finest moment in the famous white shirt was his battling performance in the 2014 World Cup final in Rio.

He absorbed everything the Argentina midfield threw at him to help Germany secure a 1-0 extra-time victory as Mario Goezte's winning goal gave die Mannschaft a fourth title.

“Winning the 2014 World Cup was an historic and emotional moment for us, which will not be repeated again in my career,” said Schweinsteiger.

“Therefore, it is the right time and sensible to finish now and to wish the national team all the best for the qualifiying stage and the 2018 World Cup.

“Finally, I just want to say to our fans: 'it was an honour to have been able to play for you, many thanks for everything that I was able to experience with you'.”

Schweinsteiger says he regrets Germany's Euro 2016 exit to France as Antoine Griezmann netted twice in the hosts 2-0 semi-final win in Marseille before losing the final 1-0 to Portugal in Paris.

“Jogi Loew knew what the Euro 2016 in France meant to me, the title I absolutely wanted to win, which hadn't been brought to Germany since 1996.

“It wasn't to be and I have to accept that.”
