It's not like the BVB board would push him out if he expressed his desire to stay, and help his team back in to the CL. And we know a team in CL finds it easier to find quality replacements for out-going first teamers. I can understand if his wish is/was to experience a diff league and such. But there is a manner of making that transition. As far as I'm concerned, he's taken the easy way out, and not honored his current role.
you always talked about him like he was some really masculine and honourable guy. he is just like every other footballer.
