Arsenal defender Laurent Koscielny says he's improved this season.

The France international's form has led to interest from Barcelona and Bayern Munich.

"I think I have [progressed]", Koscielny told the official Arsenal matchday programme. "I had injury problems in the early weeks - a calf problem in pre-season that it took me a while to come back from.

"But I think the experience of this season can help me in the coming years. I feel more confident and sense that I have more authority on the pitch these days. It is a good sign for the future."
