If that's the case why wouldn't he come out and say that instead of this birthday story which is doing him no favors whatsoever?I'm going to play devils advocate here.
Perhaps there is something that we are NOT aware of that is causing this nothing news to blow up. Maybe the owners have a grudge against people with a particular colour of skin and didn't want to shake hands. If he was at a reception with the owners and no one shook hands I think you may understand his anger.
Let's wait for more "facts" to come out. As it is, the story is so trivial that many if us are tearing it as another primadonna footballer stamping his feet.
