Arsenal are preparing a bid for Borussia Dortmund fullback Lukasz Piszczek.

The Daily Mail says the Gunners have identified the Pole as a replacement for Bacary Sagna if they are unable to resolve the Frenchman's contract dispute.

Piszczek has only been with Dortmund since 2010 following a free transfer from Hertha Berlin.

The 27-year-old has developed into one the most impressive right-backs in the Bundesliga and is a mainstay in the Polish national team.
