Bayern Munich defender Holger Badstuber has admitted that there is still work to be done before he is fully match fit.

The 25-year-old has spent much of the last three years on the sidelines with two cruciate knee ligament injuries.

However, following his appearance in last night's 4-1 win over Koln, the centre-back has revealed that although there are still improvements to be made, he is getting sharper with each passing game.

"It was hard work. I'm becoming more and more stable personally. It's great that I'm getting playing time and match practice," he told the club's official website.

"Every game and every minute is helpful, but there are a few things to improve."

Badstuber has made eight appearances in all competitions this term.
