Per Mertesacker is reportedly considering international retirement, according to the German media.
Germany are still toasting World Cup success, but they have already received a stark reminder of the need to evolve.
Two key figures in the side Miroslav Klose and Philip Lahm have already confirmed their retirement, and while the 36-year-old striker's decision was no surprise, it emphasises that Germany can no longer ignore their lack of a top class forward.
Lahm, 31, was more unexpected, and now reports are emerging that defender Per Mertesacker could follow.
Mertesacker has recently returned from the international break, but is a doubt to face Crystal Palace at the weekend due to a lack of training time.
The centre-back played in a staggering 66 games for club and country last season, and it is reported this is the reason for him considering his future, as he prepares to turn 30 at the end of September.
Mertesacker even missed key games during the World Cup due to niggling injury issues, and knows another lengthy campaign lies ahead with the Gunners competing on all fronts, and Euro 2016 qualifiers to negotiate with Germany.
If he were to retire from the German side, then it will only be good news for Arsenal, who will see a fresher Mertesacker throughout the season, and not have to worry about his fitness when he returns from international breaks.
