yes, this is why i think if we were Ambramovic's Chelsea we'd be showing Arteta the door and getting someone in who has CL experience, knows how to rotate players and adapt tactics and style to suit the circumstances.
we won't though and sure, we probably should give him the chance to show he can learn from his mistakes, but i think we could well fall disastrously short next season.
tbh if we do terribly and it means he goes, then it could well be a blessing in disguise, rather than have years of his just doing well enough to keep his job but us always being fundamentally flawed
of course the irony is that at the piont when he is a genuinely good manager (if he ever gets there), he'll bugger off from his own personal training ground to Barca or somewhere
