The type of players we're getting now, I don't think a leader of the Barton ilk is that major. We've still got influential players out there maybe not in the in-your-face style of Barton, but Coloccini, Tiote, and looking likely Cabaye are players who'll get the team going in a different way.
And if the players do need a rollocking, I've no doubt whatsoever that Carver & Stone (wow, I've just got that some people carve stones...genius) will be at hand to dish that one where necessary.
I guess this is so but I'll miss the "Barton in-your-face approach" tbh.
