Bayern Munich striker Miroslav Klose has impressed Germany head coach Joachim Low in recent training sessions and may yet earn a starting spot at the World Cup finals.
The 32-year-old frontman was a bit-part player for his club last season and has been playing catch-up as a result, but Low has seen an improvement in recent times.
He commented: "He has worked hard in recent weeks and I felt for the first time on Tuesday that he felt better prepared physically.
"He is a very important player for us, but the situation was not easy for him last season.
"Bayern won the league and cup double, he has not played much and has a strong desire to compete. But he has worked hard in our training sessions."
