By saying sorry Arsene but what you're doing isn't quite right, 7 trophyless years suggests your wrong, you need to try other things and listen to some other view opinions to try and reverse this downward spiral.
My point about Bould is that he's been surrounded and enchanted by the Wenger way for 11 years, he's hardly like to really challenge him, everyone at the club seems to think he's the 2nd coming after all.
