Germany winger Andre Schurrle announced his retirement on Friday, aged just 29. On Wednesday, Borussia Dortmund cancelled the former Chelsea player's contract by mutual consent with a year left to run and Schurrle said the decision to retire "has long been maturing in me". "You always have to play a certain role to survive in the business, otherwise you'll lose your job and won't get another one," the 2014 World Cup winner told <em>Der Spiegel</em> magazine. "Only performance on the pitch counts. Vulnerability and weakness shouldn't exist at any time," he added having come to the conclusion, "I don't need any more applause".
