In a squad of ageing players, the 20-year-old Hertha Berlin midfielder stands out for his youth and vibrancy.
Often compared to Liverpool's Michael Owen, he can expect similar levels of hype. But the reputation is not without justification.
He made his international debut in a recent warm-up match and was the only positive aspect of a disappointing 2-1 defeat to Holland - the Germans' first defeat on Dutch soil in 75 years.
He had coach Erich Ribbeck singing his praises. "He really tried to bring the ball forward and he did make a difference," he said.
