Hannover director Martin Bader has revealed the club are keen to re-sign Arsenal defender Per Mertesacker.

But the Bundesliga 2 chief has admitted it may be difficult with his side now playing in Germany’s second division.

Mertesacker, 32, came through the ranks of the Hannover youth academy and his former club are battling for promotion back to the Bundesliga with the side currently sat in second.

He left Hannover for Werder Bremen in 2006, before leaving Germany for the Emirates in an £8million deal in 2011.

Mertesacker’s contract at the Gunners expires at the end of the season and Bader has revealed the German side are hopeful of luring him back to the HDI-Arena.

“All know is what Hannover means for Per, and maybe we can inspire him again for 96,” said Bader to German publication Bild.

“The issue of Per Mertesacker is we’re currently not high on the agenda. It’s obvious, because we are in the second division and he is the captain of Arsenal. A lot will need to come together, so that a return is possible. The first requirement is that we ascend. “

Right now that’s far away and sounds crazy. But in football many things are possible.”

Mertesacker has been out since the start of the season with a knee injury that is expected to sideline him until the new year.

The defender, who was a first team regular until his injury, hinted that he could leave the club in January with new signing Shkodran Mustafi building a good partnership with Laurent Koscielny in defence.

The Gunners are currently sat in third place and two points behind league leaders Manchester City.

They will face a tie against struggling Swansea after the international break.

In other Arsenal transfer news, the Gunners are interested in signing young striker Andre Silva from Porto.
