There was an unfamiliar sight on the Werder training ground on Thursday. Michael Lang, who is usually a right-back, is practicing on the left side of the defence. It’s not necessarily going to become a habit for the Swiss man but for now it’s happening. "It’s like when you drive a car in London, it’s unusual at first," he said. "I'm right-back, that's where my strengths lie." But the 28-year-old knows he must do what’s best for the team. "In the end, the coach makes the decisions and if I'm needed elsewhere, I'll play there too."
