The 32-year-old started his career in Germany with FC Schalke 04 before switching his allegiance to Bayern where he has just completed his fourth season.
He made his international debut back in 1997 and became one of Rudi Voeller's most trusted players in the World Cup qualifying campaign.
Arguably Germany's best man marker, he is been a dependable presence at the back.
He also enjoys the occasional foray in attack.
