I think you're right that we do this more. Jose HAD instilled this argumentative streak in the player, but you know what? That's fine. As long as you only do it when you genuinely feel hard done by! And many times we have in the past, in this season, but clearly that's not what the players are doing if you look at the reaction to Ashley Cole's lenient booking against Spurs.
I would suggest it is as much Grant not doing anything about it than worsening it. On the one hand you'd think Ten Cate, being the disciplinarian one, might stamp his foot down, but no, instead he is probably just as argumentative as Mourinho.
It is definitely a problem, and it's you that's convinced me of that misschief. I wouldn't have a non-Chelsea fan telling me such a thing even if it IS obvious!
