Borussia Dortmund are lining up a move for Arsenal defender Laurent Koscielny.

The Daily Mail says BVB are monitoring developments with Koscielny, 33, who could be allowed to leave this summer.

The German giants are looking to bring in defensive reinforcements and experience after narrowly missing out on the Bundesliga title to rivals Bayern Munich.

Koscielny made his comeback for Arsenal last season, following a long spell on the sidelines recovering from an Achilles injury.

He is contracted to the club until the summer of 2020, with Arsenal knowing the only time to recoup a fee on the player would be in the current window.
