The thing I can't help but wonder is if Delph thinks to himself, "I've got trophies in my cabinet, which is more than any of this lot have ever accomplished. So if I want to yell at my teammates and talk down them, that's my right. That's what being a 'winner' is all about." Given the fact that he was a bit-time player at City and won those trophies primarily on the backs of the greatness of other players and coaches, that doesn't sit right with me.
Regardless of the incident, his impact on the field for us has been minimal at best. For the record, I was never keen on his signing. To me, this should serve as a reminder that next time we look at signing someone like a Delph, Rooney, Eto'o, etc., we should remember that being part of massively talented and successful teams doesn't mean you can just transfer that success over to another club. If the best reason you can come up with for signing someone is that they'll provide "leadership" and a "winning mentality" rather than on-the-pitch attributes, then it's best to swerve.
