Hmm perhaps you are right he has in recent times had a much better defense in front of him then Wiese now more than ever. But I'm also taking into consideration Wiese's horrible match with Frankfurt - so yes maybe they are equal.
On a side note isnt Adler also an overall 84?
Adler has in PES 2012 82 - (with the same stats) in PES 2013 will it be 83.
He was 3/4 year without practice so it could be okay. But I could make him to a 84 or 85, because he plays a great comeback and season in Hamburg. - He could return to the German NT...
