Bayern Munich winger Arjen Robben has signed a contract to extend his stay with the German champions until the summer of 2018. The former Chelsea player’s current deal was due to expire at the end of the season but he is now tied to the club until he is 34. “In his position Arjen is one of the best players in the world,” Bayern Munich’s executive board chairman Karl-Heinz Rummenigge said. “He’s been here for almost eight years and has become a key part of the club.”
