Let's be honest, Niasse treatment notwithstanding, his methods of working and man management have come under scrutiny wherever he's been it seems. We had a post-Martinez bounce in which it could be argued anyone with a degree of professionalism and managerial experience would have lifted that group of players from the depths they were in, and he got an extra 20% on top due to people wanting to impress a legend of the game. Since then it's unravelled quickly and he's alienated quite a few popular players.
Looking back his treatment of Barkley was met with mixed reactions at the time but he was given the benefit of the doubt as he was Ronald Koeman. Maybe now, if Barkley signs, we'll see a rejuvenated Ross freed from the old self-limiting shackles and given a fresh start. Although God knows where he'll play seeing as we have about a dozen players for about three positions now.
