I don't think you can make such statements when you're playing against a fantastic footballing entity. Many teams in the PL have done no better than Cardiff have been doing so far. Cardiff's style dictates that there won't be periods of possession. It's get it and hit it, or run with it.
I don't think Cardiff will be in the top 6, Christmas dictated that, and for every game Cardiff lost over that period, an extra team joined the queue to go above them.
Warnock won't be changing anything as the result of today. He'd be daft to do so.
