Bundesliga giants keen on Arsenal defender
The German international has endured a turbulent spell in the Premier League since his arrival in 2011, with his sometimes languid playing style opening him up to criticism.
Despite seeing his first-team opportunities rationed for much of last season, the 28-year-old has become a key man under Arsene Wenger this term.
But, Wolfsburg are keen to lure him back to the Bundesliga at the end of the season, as the Gunners step up their pursuit of other defensive targets.
Swansea’s Ashley Williams is said to be on their radar, and if a move is made, it’s likely that one of the north Londoners’ current defensive men will have to make way.
Wolfsburg’s sporting director Klaus Allofs worked with Mertesacker at Werder Bremen, and is keen to set up a reunion with the towering centre-half.
He could be tempted to return to his homeland, with his chances of football at international level likely to increase if he is playing regularly in an environment where he is exposed to the German side.
Mertesacker arrived at the Emirates Stadium at the back end of the 2011 summer transfer window, as Wenger made some late additions to his underperforming squad.
