I can't comment on neither claim as i have never been present to witness is....same as every single person on this forum and we are basing most opinions on internet trash news.
What players didn't want him back? By that point, most of the first team had expressed their own desire to leave and possibly even handed in their own notice's (including some of current squad members might i add), lots had already left for free (Smith, Windass etc...), so most of the squad at the training ground had never actually played a first team game had probably had no right to have any opinion!!
Röhl came to us as an unknown entity but quickly built a solid reputation (saving us miraculously and even progressing us in extremely difficult circumstances) and is showing signs of immense potential elsewhere...why any of our fans would have any hard feelings towards him, seriously baffles me!! Our loss is someone else's gain.
