Ossie was a top midfielder who knew the score which is why after helping el Fraudo out on his quest to 5th he was then shafted along with Pienaar and basically anyone else who wasn't a mute crab. He knows the score with Barkley and I've no doubt that once he's over this bump he'll be a far better player under Koeman. Martibez's reign of terror devestated Ross and set him back years. He really would have been better under Moyes, absolute no coincidence in my mind that Ross' good form in 13/14 so gleefully attributed to Martinez was just the continuation of his good performances back end of 12/13. What we saw under the rest of Martinez was the systematic destruction of a number of players Ross included. That overhang is still there now but Koeman is the man to nurse him to good form again.
Barkley's form was great for the first half of last season, then he just seemed to hit a brick wall, his confidence looked shot after the crowd started getting on his case when he made a mistake, it got to the point for me where as soon as the ball came to him he just wanted to get shut of it.
Barkley is deffo a confidence player, and with Koeman taking no prisoners, and he wouldn't think twice about dropping Ross, Barkley IMO will be no different under Koeman than he was under Martinez, where Ross played some fantastic football at times, and it will be the same under Koeman.
The one huge point under Koeman is, Ross is looking so much fitter.
